To be fair, the Wii U has 720p (or 1080p in the case of Smash 4 & Wind Waker HD) assets. In theory, the NX Handheld would be 540p (going by the "higher than you'd expect, lower than you'd hope" hint from one of the GAF insiders). I get that the OP decided against including posts from GAF insiders, but I recall the GAFer being reliable.
I am so banking on the handheld being 480p. At 3.5'', it'd be higher pixel density than Vita anyway.
