With the pace of smartphone evolution moving so fast, there's always something waiting in the wings. No sooner have you spied the latest handset, then there's anticipation of something else, the next big thing.
We've rounded up the best smartphones for 2016, those we consider to be the best across all platforms, and we've regularly updated that list as the smartphone world has evolved.
You can find those in our Best smartphones 2016: The best phones available to buy today feature. If your budget is a little smaller, there is also our Best budget smartphones 2016: The best phones available to buy for under £250.
Here we're looking at those phones that haven't yet launched, those we know are coming, or are anticipated. We'll be updating this list on a regular basis, with those device rumours we think are credible and exciting, and devices just announced but yet to hit the shelves.
Next Nexus / Pixel / Pixel XL
Google tends to announce its Nexus devices around September/October but there have already been plenty of rumours surrounding the next Nexuses, or Pixel and Pixel XL as they have also been called.
Most rumours suggest both devices will be manufactured by HTC and although details are still thin on the ground regarding their designs, two big leaks have given us a good indication of the hardware we might see.
The Nexus Marlin or Pixel XL is thought to be the bigger and more powerful device with a 5.5-inch Quad HD AMOLED display expected, along with a Qualcomm Snapdragon 821 processor, 4GB of RAM and 32GB or 128GB of internal memory. Other specs include a 12-megapixel rear camera, 8-megapixel front camera and a 3450mAh battery.
The Nexus Sailfish or Pixel is said to be the smaller device with a 5-inch Full HD display reported. The Qualcomm Snapdragon 820 processor is expected, along with 4GB of RAM and 32GB of storage. Cameras haven't been detailed but the battery is rumoured to be 2770mAh.
BlackBerry Argon / Mercury
There have been numerous rumours relating to various BlackBerry devices that are expected to launch sometime this year. The latest leak suggests we will see three BlackBerry devices appear before the beginning of 2017, the first of which launched as the DTEK50.
The second rumoured handset to be coming is the Argon, which is set for an October launch. It is reported to offer a 5.5-inch Quad HD display, SD820 processor, 4GB of RAM and 32GB of internal storage. A fingerprint sensor, 3000mAh battery, USB Type-C, 21-megapixel rear camera and 8-megapixel front camera have also been reported.
The last device is being called Mercury, but it was previously known as Vienna. This handset is said to be following the more traditional BlackBerry form factor with a large touchscreen and physical QWERTY keyboard. Specs include a Qualcomm SD625 processor, 3GB of RAM, 3400mAh battery, 18-megapixel rear camera and an 8-megapixel front camera.

Apple iPhone 7 and iPhone 7 Plus
Apple has announced its latest iPhones, iPhone 7 and iPhone 7 Plus. Both offer a similar design to the iPhone 6S and iPhone 6S Plus, but they make a few changes worth noting.
For starters, the antenna bands across the rear of the devices have been moved to just the top and bottom, making for a much cleaner design. They also both ditch the headphone jack and introduce stereo speakers instead.
The iPhone 7 Plus adds a dual rear camera to the mix, with one 12-megapixel wide-angle sensor and another 12-megapixel telephoto sensor, while the iPhone 7 sticks with just one 12-megapixel sensor. Optical image stabilisation is on board both devices.
Under the hoods, the two new iPhones feature the A10 Fusion processor and they come in 32GB, 128GB and 256GB storage options. Pre-orders start on 9 September and they will go on sale on 16 September with iOS 10. Both ditch the Space Grey colour but add Jet Black and matte Black offerings.
LG has announced its new flagship - the LG V20. The device is the first smartphone to run on Android 7.0 Nougat out of the box and continues what the LG V10 started.
The V20 offers a dual-camera setup on the rear like the LG G5 and the company claims it will "be a new standard for premium phones with more enhanced multimedia capabilities." It features a metal body with MIL-STD 810G drop protection, a circular fingerprint sensor on the rear and it comes with 32-bit Hi-Fi Quad DAC capabilities.
Under the hood, the LG V20 features the Qualcomm Snapdragon 820, 4GB of RAM, 32GB or 64GB of internal storage and a 3200mAh removable battery. LG has yet to announce pricing and availability but it will launch first in Korea.
Sony Xperia XZ
Sony announced its next flagship - the Xperia XZ at IFA 2016. The device takes over from the Xperia Z5 and it sits at the top of the X Series that launched at MWC 2016.
The Xperia XZ features the same OmniBalance design we have come to expect from Sony devices, though it offers a squarer top and bottom in comparison to previous handsets. The edges are round and there is a new feature called Loop that sees the screen look as though it is wrapping around. There is also a new camera on the rear with triple sensing technology.
In terms of specs, the Xperia XZ features the Qualcomm Snapdragon 820, 3GB of RAM and it is available in 32GB or 64GB storage options, both of which support microSD. USB Type-C is on board and there is a fingerprint sensor built into the side power button. It is also IP68 water and dust proof. Pricing has yet to be announced but it will debut in October.
It might be surprising to find a mid-range handset like the Huawei Nova and Nova Plus in this list, but that perhaps says more about Huawei's progress over the past few years. The regular Nova is the more interesting device, partly because of the wonderful design. It looks like a mini Nexus 6P and we like that a lot.
Aside from he visuals, the metal design gives a solid build, topped with a 1080p 5-inch display, with power coming from the mid-range Qualcomm Snapdragon 625 chipset. There's 3GB RAM, 32GB storage and support for microSD. The 12-megapixel camera on the back is pared with an 8-megapixel front camera.
Perhaps the only downside is that you have to get to grips with Huawei's EMUI software interface layered over the top of Android. But, for the €399 asking price, that's something we're happy to deal with.
Motorola Moto Z (2016)
The Moto Z launched in the US as a Verizon exclusive over the summer, but it's now hitting the UK, priced at £429.
One of the things to note about this handset is that it loses the 3.5mm headphone socket - like the iPhone 7 - but Moto uses this to push for a slim design.
Offering something a little more unique on this flagship-spec smartphone, the Moto Z's biggest selling point is the compatibility with a range of Moto Mods. These are modular accessories that attach to the rear of the headset to let you do more. That might be as simple as a battery case, but extends all the way up to a Hasselblad zoom camera.
It's unique and exciting, and soon to arrive in the UK.
Microsoft Surface Phone
The Surface Phone is something of a Windows phone holy grail. With Nokia then Microsoft Devices producing plenty of Windows Phones, the spectre of the Surface Phone has been hanging around as the idea of the ultimate Windows mobile device. Given the recent sale of virtually all of its phone patents, and announcement that it's no longer focussing on Windows Phone development, the Surface Phone may never see the light of day.
It's rumoured that the new premium device will be Surface branded and Intel powered, possibly coming in three different variants. Given the same team behind the Surface Tablets are said to be behind the Surface Phone, you can expect a solid build if it ever does appear.
There's also the suggestion that Surface Phone will run a brand new update of Windows 10, aiming to capitalise on the branding and offer the ultimate experience. Launch originally wasn't expected until the latter half of 2016, but this has since shifted to beginning of 2017. That's if it appears at all.
