I think this is a mistake to launch this so late in the generation (although we could be looking at a 10 year generation this time). No pervious games will support it obviously, MS has very little internal development to support this with and 3rd parties will almost wholly ignore it unless the adoption rate is enormous. After all HD games are made for PS360 not just 360 so to be worthwhile to include such a radically different control scheme there would have to be a huge chunk of 360 owners with it. At least 30% - minimum.
In the short term at best EA may port over Boom Blox and Ubisoft some of their party games (enjoy!). This will not be anymore successful than Eyetoy on PS2 was.
Also, I would prefer to hold something (like a wiimote or something) if playing tennis or golf instead of nothing at all - that would just seem weird.
