As you may already know, Mobile World Congress is just around the corner, Feb 17th to be exact.  It will be hosted in Spain like any other year.

We expect to hear something big in a little more detail, that's the Windows Mobile 7.0 which wasn't mentioned at all during Steve Ballmer's keynote speech at Consumer Electronic Show.

From what I read on Mobilecrunch:

WinMo 7 is essentially a copy of the Zune HD's kernel. It comes in one screen size and will work best on OLED devices. Microsoft will give official specs to hardware makers and force them to comply or else refuse them access to the OS. This includes a regimented screen and RAM size as well as a minimum processor speed.

If you haven't guessed, Microsoft is about to get all Apple up in this piece.

The UI looks just like the Zune HD's with some phone controls built-in. The HD has defined the interface and the use case here, so expect a capacitive multi-touch screen with plenty of media controls.

I guess no one knows until we see it in action, we will post updates as soon as we find out more info.
