One of the devices we’ve been most looking forward to getting our hands on at Mobile World Congress next month is the HTC M7, a new flagship Android smartphone that’s set to introduce HTC’s new Sense 5.0 user interface. If the latest rumor is accurate, however, the M7 won’t be at MWC; it’ll get its own launch event the week before instead.

Google is said to be preparing a second-generation Nexus 10 tablet for Mobile World Congress in Barcelona next month. The device will reportedly offer a quad-core processor and faster graphics, making it a significant improvement over its predecessor — which was only launched last November.

Rumors surrounding the Sony Xperia Tablet Z first surfaced last week, and we expected Sony to confirm them at Mobile World Congress in Barcelona next month. But in Japan on Monday morning, the new flagship tablet was unveiled. And boy, does it look good.

The Sony Tablet S could soon have a successor.

Specifications for Sony’s upcoming Xperia Tablet Z were leaked on Wednesday, and we were looking forward to seeing the slate’s grand unveiling at Mobile World Congress in Barcelona next month. But according to one Japanese carrier, Sony’s new flagship tablet will be unveiled on the company’s home turf on January 22.
