(Pocket-lint) - We already knew that Samsung wouldn't be unveiling the Galaxy S8 smartphone at MWC but we have instead been preparing ourselves for the launch of a new Galaxy Tab S3 tablet. But Samsung has allegedly confirmed the Tab S3 will be joined onstage by 2 other tablets, according to SammyHub.

One of those other tablets is said to be the Galaxy Book, a Windows 10 touting tablet that will compete directly with Microsoft's up and coming new Surface Pro.

MSPowerUser has previously uncovered evidence of the Galaxy Book after a new Book Settings app appeared in the Windows App Store. The app references features including battery life extender, pattern log-in and pen. The Galaxy Book is expected to come sporting an AMOLED display and S Pen stylus included.

As for the third tablet, SammyHub doesn't allude to anything, but Droid Report references a report from Forbes that suggests Samsung will reveal a refreshed Galaxy TabPro S2 as a more wallet-friendly 2-in-1 laptop/tablet hybrid. The TabPro S2 is also expected to come running Windows 10, have a 7th gen Intel Kaby Lake core i5 processor, 4GB of RAM and a 5,070mAh battery.

The predicted 12in screen should be Quad HD resolution, and there's thought to be a couple of versions: Wi-Fi only and Wi-Fi with LTE mobile connectivity.

We have a much clearer idea of what to expect from the Galaxy Tab S3 though, as several renders and rumours have leaked in previous weeks. It should ship with an S Pen stylus, but interestingly there won't be a port to store it in. It's also expetected to feature a keyboard dock similar to that of the iPad Pro, but won't come supplied with a keyboard accessory.

We'll know everything at 6pm (GMT), and you can see everything that's revealaed for yourself by watching the livestream.
