And the question wasn't addressed in the video.
Can this function like a normal tablet? Will I be able to remove the controller modules and carry it around and read email, use Chrome and Google Now and Microsoft Office apps and snap photos? Or is this a dedicated gaming machine that's just modular?
If the latter, I wouldn't buy it. If the former, I'd buy it to replace my current 8" tablet, as a tablet PLUS gaming experience. But I need a tablet, and I don't want to have to have TWO tablets just to get slightly better gameplay on one of them.
If it's a one tablet concept (would have to be Android, I assume, to have the ecosystem) then great. If it's just a game console with fancy industrial design? Pass. I have good enough gaming on my current tablet.
