Aside from all the new phones we're sure to see in a couple weeks at Mobile World Congress, we're totally geeked out over what Microsoft is expected to announce.

Of course there's Windows Mobile 6.5 We've seen the leaks. But it's Skybox, Skyline and Skymarket that have the longer-term implications. ZDNet's Mary Jo Foley shares some thoughts of what we might find in Skybox, with help from some unnamed sources. The bullet points on the upcoming cloud hub that will manage much of your user data and information:

• Skybox 1.0 will go into beta this month. The beta will be free, and ad-supported.
• Skybox 1.5 will come in the summer and see a free service and premium paid service.
• Skybox 1.5 will be available on Windows Mobile 6.1, 6.5 and a few non-WinMo phones.
• Skybox 2.0 is the big cheese. There will be integration with Windows Live Services. You'll manage your phone, ringtones, apps, music, video, backgrounds – all from the cloud.

This is starting to get very exciting. And we'll be on the floor in Barcelona Feb. 16-19 to bring you all the goodness.
