Well, my first thought seeing this was like wtf are they trying to achieve with this device?
I mean ok, they are trying to resurrect the Vita, but with a stationary device? Really? What audience are they even aiming at? 
The stationary console market is almost dead in Japan. Most people there spent hours of travelling in a train every day. So they try to kill time on the way and play mobile games. After a 9- hour work day and spending hours on the way, most people want to chill with their family or just watch TV, but certainly not playing the video games they already played on the way to work, again.
So yeah, it's for the western market then you will say, but who besides a real small minority would want to play mobile games on the big TV? 
The western market is split into casuals who just want short fun on the way while swanking arround with their newest mobile device and the core crowd which is way too heavy into blockbuster shooter and sport games with fancy graphics.
I think this device is a waste of resources.
