I wouldn't really expect Nintendo's next handheld to be as powerful as the Wii U, or the battery life would be terrible.
I could be wrong, but I don't see the big value of compatibility for handheld games on a home console, because inevitably they would look bad on a big screen. Not saying there would be no interest, because we know there is some interest in this kind of compatibility, but I don't think it would be a sales driver for the console. Also it probably would imply the need for a Gamepad for touch input, which I'm not sure is a good idea for cost reasons.
