Regarding the controller itself ....
The problem I have with it is I think it's more flash over function. Yes it looks interesting, but the Wii U tablet proved pretty conclusively that the touch panel is largely useless because normal human beings can't look at a TV display and a controller screen down by their waist at the same time.
Which means the point of a screen is largely .... well pointless. It doesn't change the game play in any huge way from a regular $30 controller in the vast majority of games.
I don't see how something like this wouldn't be the most expensive controller made, moreso than the Wii U tablet even. That's a highly custom LCD display in a shape no one else but Nintendo would order, so you're probably talking $100 for the controller itself, and you want a high end chipset on top of that for the console? Say hello to a $400 launch price tag.
Also I mean your hand would still obscure a large chunk of the display, meaning there's processing power/pixels draw being wasted for basically no reason. It's more flash than function.
That said I wouldn't be surprised at all if Nintendo is basically doing exactly this, lol.
