Tablets and Smartphones are a fad as a significant gaming platform.

I think you're sadly, sadly mistaken.

The people who want something more complex will buy an XBox or Playstation. In Japan it'll be 3DS.

That's it.

Smartphones are the center of people's social lives, gaming is just a silly hobby for most people, not vitally important to their day to day life. You want to see a person freak out? Take away their smartphone and tell them it's lost and you will see a flip out of epic proportions, lol. 

I don't see Wii U taking off period. Without the gimmick of motion gaming being new to drive it, it's just another GameCube -- a vanilla game system basically only supported by Nintendo with some token third party support that appeals to a niche market.
