About that 1080p30=720p60:
That is only correct on GPU level. Mainly because most games today are limited by shaderpower graphics wise.
On the CPU level that is wrong, and CPU's still do a lot of work. Don't know why people forget that nowadays.
About Zelda U: I'd expect 720p with locked 30fps. That doesn't seem to impressive, but giveen it is open world, there's all that grass and other nice effects it seems likely and it would actually be better than most open world games on last gen.
Far Cry 3 and 4 where slightly sub HD with 20-30fps. Skyrim was 720p i think with more or less often below 30fps.
