MS isn't making a gaming handheld. This is merely referring to the ZuneHD. It already has games and XNA compatibility. the only addition I see here is the Live Anywhee stuff. Which would be great additional functionality for it. This is still an mp3 player at heart. The touch screen will make playing games much better than the current Zune. Also, the nVidia video card that will be in it is pretty good as well.
You guys think they are entering a new market or something but that is not the case. They are just upgrading the Zune. XNA, XBLA, and Live make for an already compelling catalog of games. But then you have the Zune Marketplace which provides you with unlimited songs. I don't think the merger of Live and Zune will only be on the Zune, i think the merger will be seen on the 360 as well.
