No this is incorrect.

True its correct that GPU load is roughly the same, as in about twice as many pixels at half the frame rate equals half the number of pixels at twice the framerate .

But the CPU load doubles going from 30fps to 60fps. Looking at this wide open game I think the CPU load will be pretty high already at 30fps. The Wii U's CPU isnt all that powerful to begin with, if you are CPU bottlenecked it doesnt matter what resolution you run it at.  

Scale is realative, as I was referring to both content and physical size. The map may be bigger than skyrim, but amount of content in it, such as dungeons and caverns outside the story, will only be known on release.

You admit it, the size of the game when reffering to both content and physical size will only be known on release, so do not say "An open world Zelda that looks gorgeous and almost the size of Skyrim?" when you do not know. Sound good? Do not claim a game is bigger when one isn't released yet and you KNOW that.

Also, it might be a linear track, however, that is not my point. Open world might be harder to achieve a smooth 60fps, but as you said, Nintendo is basically a god when it comes to optimizing. They did that with a lot of things. Plus, Zelda is one of their main franchises. I doubt they would make it 30fps. They know it would be bad.

It is. It won't.

The CPU generally handles tasks like AI, animation, and physics. From what we've seen so far, Zelda looks much more GPU/Memory bound; a good fit for Wii U's hardware, in other words.

There is an absurd amount of content and locations within Skyrim, so i'll use "almost" until the game actually comes out, since it's the only word that I can use to compare them. 

In either case, bringing a game to 60fps for a console like the Wii U is especially difficult, because to maintain high framerates requires a decent cpu. With the power it's 3 core cpu has, it COULD reach 60fps, but mainating that in combat and in events with special lighting, particle, and water effects wouldn't work. Bayonetta 2 is a clear example, as it is 60fps much of the time, but during combat in some areas (underwater near fimbulvetre)it drops down to 50. 

Actually, I believe the only Nintendo games confirmed by Digital Foundry to have no AA are Mario Kart 8 and Smash Bros, the latter of which was 1080p. Hardly "many times." They even praised Smash's IQ.

XCX will be 720p, to allow for a larger and more detailed world.

I would be fine with 720p 60fps

wii u's gpu is a gpgpu, meaning it can do a lot of stuff a cpu does. and there a big xageration over wii u's cpu power, generally because people only compare clock speed and ignore the rest.

Yeah, from the demo it doesn't look llike much is going on but I'm thinking about the comments about it mirroring the real world. This could simply be day cycle day/night time cycles or it be much deeper with wildlife,  complex AI with scedules etc. I'm just assuming that what we saw in the demo isn't a good representation of the majority of the game because its extremely empty.
