As much as I hope that this will be good I have to keep my expectations reasonable. Not because I don't think Nintendo is good, I love them.
But c'mon, they're standing under a fucking waterfall of money with their "everyone can do this!" ideas. The Kinetic is just unintuitive and it's characters are just creepy, Milo and that Tiger thing.... And PS3's are not something everyone buys, they scare people off with their "we're totally better then 360" stuff.
The Wii hit a niche market by becoming a toy that flashes lots of lights and gives you completions.
I hope it works out though!
