I for one do not think that everything should be motion control. I like just a controller in my hand to play a game. The only games on the Wii that I play with motion controls in Wii Sports & Wii Sports Resort. I tried playing other games with the motion and did not like it at all. When I play Mario Kart I plug in the nunchuck and steer with that. I for one hope that the next gen will not go to mainstream motion controls. If they are added as a peripheral and there are some games that support them then that would be perfectly fine. And if the next gen was just motion controls I would probably skip it and just stay in the current gen and just speed up my buying of all the PS3 and X360 games that I want to play. Or I'll go strictly handheld.
End of 2009 sales predictions:
PS3 - 33 Million 360 - 40 Million Wii - 75 Million
