CES 2015 has only just arrived really but it's already apparent what the major products and trends of the show will be. Just listening to people chat in the halls, or closely observe the posters outside the convention centre and you can tell exactly what to expect in the world of consumer electronics in the coming year.

Some of the trends discussed are fairly obvious, carrying on from similar threads last year, and some are surprising. For example, we thought we'd see much more in tablet technology this year, but manufacturers are either mainly leaving that genre of tech to Mobile World Congress in February or the bubble has indeed burst - we might well have reached tipping point.

Instead, here are the eight trends that have emerged from the CES so far and our thoughts on each. Enjoy.

It's not a new technology and has been on the horizon for while as a premium TV resolution, but 4K is about to take over from Full HD. If CES 2015 is anything to go by, it won't be long before manufacturers stop making 1080p televisions below 55-inches, opting for 4K Ultra HD TVs only in the larger category.

The most promising result of this is that we fully expect 4K TVs to be available at far more attractive prices in the coming year than they were in the last. The 3840 x 2160 resolution revolution will be priced at a level many will be able to afford and that might prompt content suppliers to get a wriggle on in giving us significantly more native video to watch on them.

Along with 4K, the other major trend that CES 2015 will possibly be remembered for is "Internet of Things". Of course, that term has been bandied around a lot of late, but rarely has it applied so much to so many of the products seen at the show.

Just about everything in 2015 will have some form of wireless connectivity, it seems - often linking to a dedicated smartphone or tablet application, sometimes the internet and the cloud. From baby bottles to belts for trousers, via cookers, washing machines, vacuum cleaners and even wardrobes, there is a device at the right price for every aspect of life that supports Bluetooth, NFC, Wi-Fi or a combination of them all. Now, if they could only get them all to talk to each other. Hmmm, maybe CES 2016.

When Samsung and LG unveiled curved TVs a couple of years ago everybody though they were testing the water with a gimmick to make sets a little more interesting. After all, TV sales have plummeted in the last few years and the industry needs something to provoke people to upgrade their already decent LED tellies.

That will no doubt be 4K, but curved TV form factors are not only going away, from the floors of CES 2015 other manufacturers are getting in on the act too. And not just big brands either, Haier and other Chinese TV companies have unveiled their curved sets, so perhaps there's something in it after all.

We had a hope a while back that somehow the TV manufacturers would sit down and agree on a unified smart TV platform that users can access no matter the brand. That was a pipe dream for sure, but you never know.

And in some ways it has become a little like that, with Sony, Philips and Sharp all adopting Android and the Lollipop build no less to power their TVs. Buy TVs from the three this coming year and you may will able to use your own Google Play account to download apps, regardless of the manufacturer.

Samsung, LG and Panasonic continue to rock the boat though as although they've plumped for existing operating systems for their TVs too, they are all different. Samsung has its own flavour of the open source Tizen, Panasonic has Firefox OS and LG sticks with the webOS platform it acquired a few years back. Still, they will all offer better smart TV abilities than ever before.

When Philips first offered a 21:9 TV to match the aspect ratio of many movies several years ago people clearly thought it too weird a concept. However, plenty of other companies are latching onto the idea of late, showing 5K (5120 x 2160) TVs with a wider than normal screen.

It still might fall flat though, as although there are no black bars top and bottom when watching a 21:9 film on Blu-ray, there are black bars either side of the screen watching a normal 16:9 TV broadcast. Sharp has a concept display that answers that question, which adds a social media sidebar beside broadcasts, but do you really want that or something similar running all the while during Eastenders?

There is a lot of talk around high resolution audio at CES 2015 and rightly so. To hear a track in a format as close in quality as the artist originally intended is the Holy Grail for all audiophiles and genuine music fans. Manufacturers now agree, so many products are coming that will let you do just that.

Perhaps our favourite so far is the return of the Sony Walkman in the form of the ZX2 - partly because of the performance it promises, but mainly because it's the, you know, Walkman.

Admittedly, the portable music player will cost almost £800, but not only will it deliver 24bit 192kHz audio it's got Walkman on it. Did we say that already?

The other TV technology that has been adopted by LG and Samsung, albeit under different names, promises to improve picture quality for LCD TVs, breathing new life into a tech that many love already. Quantum Dot and SUHD technologies both use layers of nano-crystals that can emit light in different colours depending on their size and therefore enhance the colour reproduction of sets.

LG

This, we are told, creates more natural tones for both companies' tellies and will perhaps put you off opting for OLED for yet another year.

Yes, it won't blinking go away. We're not talking about the art of taking pictures of yourself and friends by holding your camera or smartphone away from yourself, that's being going on for years. We're talking about the word "selfie" - it was so ruthlessly hijacked by companies to use as a marketing buzzword that we're sick of it now.

Lenovo

However, there are signs that we're in for another year of products tagged with the word. For a start, just about every smartphone announced during the show has a front-facing camera that is at least 5-megapixels, aimed squarely at the "selfies" market. And Lenovo has even launched a dedicated front-facing flash for smartphones, called the Vibe Xtension Selfie Flash. Enough already, please.
