I have to admit, the following worries me a bit:
I don't want any of the gimmicky crap, if I did i'd buy a 3DS. What's wrong with just making it a good gaming machine without having to shoehorn in the latest fad?
The sixaxis is needed if they want to port PS3 games purely because the PS3 games has it.
The rear touchpad is awesome if you think about it. No L2 or R2? Who cares, just touch the back.
