I'm still confused as to why people think an unproven/failed (new eyetoy?) peripheral will somehow do better than a controller that has proven to be a success (Wiimote/Gem).
I'm not saying Gem is going to be a huge success but I don't see how it can do worse than Natal. We've seen how successful Wii Sports Resort is due to M+, PS3 should have the best version of Tiger 11 this year, the inevitable lightsaber game should also be best on PS3.
Natal just doesn't have the precision and I don't see anyone other than Nintendo who could make compelling software for it.
