I'd be excited if it wasn't just an Android device like the one I already have. I'm sure it will kick ass, but even with a controller none of my Android games can compare to my 3DS games.
The problem will all the new Android gaming consoles/handhelds is that they are limited by the lowest common denominator. Mobile gaming developers have to make their games work on a Galaxy S, Galaxy SIII, and everything in-between.
That's why Android and iOS games will never be able to compete with closed single run dedicated consoles.
I'll play Angry Birds on the go when I don't want to hall around more than one device and I'll enjoy Zelda OoT 3D when I want a real game.
