Struggling to see the market for this.
It's too big to fit in your pocket, can't replace your phone or tablet, can't compete with PS4Bone on power - let alone ScorpiPro, will be expensive, and probably won't ship with the cradle and probably will have less than stellar battery life.
On a TV it will underwhelm, on the move it will be powerful but will require planning to take it with you (unlike your phone), mobile multiplayer seems like a cool feature but two people squinting at a small screen (while all your skater friends watch excitedly) will get old fast, game prices will seem expensive compared to other mobile games and game you'll look like a bit of a tool sat using it on the train.
I *do* think they'll find a market for kids and car backseats - especially if you cache child pacifying movies and tv shows - and that could potentially be lucrative. But beyond the car <-> bedroom portability and Nintendo fans I'm not seeing where this is going to break out from just being a super Wuublet.
Though I was wrong about the Wii so IMHO and all that ....
