On the other hand, and this is more general, not related to Zelda; I believe we're going too fast; 3D needed two generations to achieve a certain level of maturity (imo there's not many "regular" games whose gameplay this gen couldn't be recreated on a 128-bit console), I genuinely believe we could have another generation to perfect the wii concept and only then needing something else because that "core mechanic" has been perfected.
I honestly think the concept to present then could be the wii U, but we have to have in mind that this concept could change the way things work.
My point being: current gen consoles are limited at this point, but still can recreate pretty much anything that the wii-u/current PC's will do/are doing running on a game per game basis; the question being how far the developers want to go (I'd like to point out how Xenoblade managed to be so ambitious on a underpowered console) current gen developers are shrinking the scope of their games so they can pull better local detail (doom 3 logic) but they also could do so much more with it.
My point is, at this point power doesn't really matter anymore, hence why Nintendo chose to bid for something new; the wiimote. The competitors recently had to do the same thing, and will have to do it for the next console; because power is not what's gonna sell them anymore (I'd also point out that Sony seemingly didn't understand this just yet looking at Vita and how they couldn't make it a focused product on some functionality rather than focusing on graphics and adding everything else they could think of)
wii U, though, changes that paradigm; it's a thing with the potential of having various controllers plugged to it so the first thing you'll want to do is having 4 controllers and player one being able to do mario kart co-op with a friend, a third gamer playing some tetris/angry birds from the wii-u-ware store and a fourth playing a virtual console/wii game. It's a game streaming workstation; except it can't really be executed this gen, because they brought back the power paradigm, from the situation any game is doable for the ballpark the platform is in, to the fact that the platform lacks the power to do so.
As a result wii-u can only be done properly when OnLive-type setups become viable or when the platform is so dammed powerfull they can assign 1/4 of the power to each app, allowing 4 people to do different things on it, and still developers not feeling like they're very limited with that cap.
