XNA 3 CTP = XNA for Zune
This CTP only targets Windows and Zune and only supports 32 bits edition of Windows, but it is already great to be able to develop games for Zune ! I have ported my Xna Chess game from Xbox 360 to Zune in just a few hours : most of the work was bitmap resizing ! Of course the Zune does not have enough power to make it competitive against native engines for Pocket PCs (such as Fruit under CEBoard :-) ) but it is really cool to have the same code running on XBox, PC and Zune !
