The trouble is, are the graphics advances of the PS3 and XBox 360 being used for advancing game play? So near as I can tell, they're not. I think Nintendo's worry is that if you have all this extra graphical power, you're suddenly obligated to spend 6 months building a "dynamic grass blade physics simulator" and ensuring that each generic enemy has his own particular set of scars and facial features, when what they would rather spend their time is learning how to program interesting new things for the player to do, not just to see.

Oh course, it would be nice if we could have both. But if wishes were horses, eh?
