Spring 2008 is when the beta is supposed to be out ... Holiday 2008 is when it should be released.
I can't wait!
Some very exciting things are coming including:
Develop 2D games for the Zune
Deploy your Xbox 360 game to anyone on Xbox LIVE!
General info on Game Studio 3.0
Things to note is that VS2008 will be used. I love VS2008, so this is great news. I would love to be able to use some of the C# 3.5 language features, but it is unknown if any of that will be available yet. Using LINQ to query a scene graph would be excellent fun!
Lots of information and as much as possible will be in my new book - Microsoft XNA Game Studio 3.0 Unleashed. More details on that to follow ...
