Theres talk of a 900p support for the next console, that could be the screen on the controller. the current one is 854x480
1080p is 1920x1080
Ipads are like 1024x768
900p is probably 1600x900 (based on photoshop's constrain proportion algorithm)
That's accurate for the older generation of iPads but all of the newer models are 2048x1536.
The gamepad could have been good. Every time I use it I can't help but notice how incredibly low resolution it is and using for off-TV play on anything other than virtual console games feels like a waste because Wii U games look so much better on the TV than on the Gamepad. And even in a small apartment with the Wii U centrally located, I couldn't use the Gamepad in my bedroom to play games or watch Netflix in the kitchen while making dinner. If it had decent resolution and range, I would have been much happier with it. There have definitely been some good uses for the Gamepad but it has never felt revolutionary or game changing.
I've been reading this thread throughout but haven't posted much because I don't have any idea what Nintendo is going to do with the NX and don't have an idea of what they should do but it's been interesting reading everyone's ideas.
