The day has come! You can download XNA Game Studio Express (Beta) from the following location on the XNA Developer Center http://msdn.com/directx/xna/gse. One reason we release beta software is to put it in the hands of the community and start getting feedback on what we'll be releasing. How you give feedback depends on the type of feedback you have. We hope many of you have already joined the XNA Beta Program through the Microsoft Connect Web site http://connect.microsoft.com. If you haven't signed up at the Microsoft Connect Site, it couldn't be easier.
