I'm curious about this, really intriguing.

Personally, I think the best thing a new console could do is fully streamline what has already been targeted with other consoles - the ability to move your game between big and little screen. If I were to be a major player designing a console right now, I'd be looking to get a console that is almost an operating system focused thing, allowing you to play games on-the-go like you do with Vita/3DS and then come home, sit the console on your TV stand, pick up a controller and continue playing your game on the big screen. The games would not be ported - it would be a merging of home consoles and portable consoles into a single system. I think that's the future, and I'm not 100% sure if the capabilities are there but it would be a way to get around that whole "Japan likes handheld gaming, Western world likes console gaming, what to do" thing.

But yeah, I've been thinking about getting a Wii U for a year or so now. Will be interesting to get more knowledge of this NX thing to see if I should hold out longer.
