I would hope so, I hope that we can finally let the SD era be behind us, on everything.
I'm hoping for 720p and it doesn't seem like such a problem with today's screen technology, but it won't exactly be a dealbreaker if it was 540p or even 480p. The WiiU Gamepad's screen resolution is fine, though it does have a weird problem with the color red. Everything that's red looks terribly pixelated.
