How bad will the fanboy motion control wars get?

I covered that with simple controls. The fact that Wii Sports Tennis is more intuitive and accessible than Pong. But anyone could have pulled that off. Well, maybe Sega, Sony and MS couldn't. Nintendo games combined with accessible controls and the inevitable return of 2D Mario (after DS success), Mario Kart and Link no longer being a cartoon character all helped sell the console to different extents.

I agree for the most part, but that isn't what you initially said.

Kart Racers, 2D platformers, 3d platformers, handheld specific games ie Pokemon, Brain Training, Nintendogs, and now motion control. Has Nintendo ever lost to any competitor?

I'm trying to think of a game genre that they've lost after successfully creating. Help? 

Nintendo's playing their A-game and Rare is dead so I don't see much chance of Nintendo being successfully copied.
