well from the info that we have now i honestly think it wont be a success, looking at the specs they are pretty high, considering this wants to play andriod games it should be a quad core device, and seeing how some specs are higher than the vita's (higher res screen, HDMI output) its certainly going to cost about or more than the vita to produce. also Nvidia doesnt make games, so they basically want to make a system that is profitable from hardware day one, resulting in the retail price to be even higher. so what do we have? a product that has no market for it. it has controls to play serious games but the games that is plays are simple low budget iOS or andriod games. its cost will put it head to head with tablets that play the same games and appeal to much more people and if u want it to simply play games on than you have vita and 3ds, wich are cheaper and play MUCH more games and MUCH BETTER games. there is NO market for it.

Thing is, this doesn't have to sell a monster amount of units to be a success.  Software for it isn't tied to it's suceess, it runs andoird and streams Steam which are both already successes.   It can be sold as a premium item at a premium cost, and as long as it, and Ouya, and the Archos gamepad, and all the other android with controller devices sell a decent amount COLLECTIVELY, then there will eb a market for more advanced Android games that use physical controls.  When that market exisits, more games will be made that take advantage of it.  Then the fun really begins.
