Disclaimer: These are solely my personal opinion and thoughts of what will be unveiled during PDC this year.

Windows Mobile 7

With the current rumors that WM7 will beta in Nov it’s a no brainer that it will be unveiled at PDC. I’m expecting a major UI update, rewritten graphics system and more integration with .NET CF. The .NET CF team has been rather silent on their blog for a while now and that’s normally a sign of big things to come. I have a inkling that the new UI will be WPF based. Since Silverlight Mobile is WPF, this would give a great chance to make WPF a full UI framework for windows mobile

Silverlight 4

Becoming a staple of PDC and Mix, Silverlight has been on some extremely fast paced development. I’m expecting SL 4 to have webcam and microphone support. Along with more .NET 4.0 features like dynamic types and the DLR.

Silverlight Mobile

It has been talked about more than once, last PDC had quite a large demo for it. I expect it to be announced probably for Windows Mobile 6.5 and higher.

Windows 8

With Windows 7 out of the way, I think we may be teased with some of the ideas they have for Win8. There has been a lot of activity on linkedin related to it. Like 128bit support, which I’m expecting is probably Intel’s Itanium successor and not meant for desktop chips.

Blend 3 SP1

MS has already said that Blend 3 will get .NET 4.0 support in SP1 and it was expected to ship Q3. I think most of this update will only revolve around .NET 4 and nothing in the way of new killer features.
