Really? You think Zelda Wii U will be delayed again for the NX?
This is what I think:
I think there is a strong possibility that the game is going to be on the NX and not the Wii U. That's pretty noncommittal of me, I'm aware. "Strong possibility" means nothing, really. But what I mean to say is this:
(1) The game has already been delayed for an indefinite period of time; (2) We
know the Wii U is doing its last lap. This could be the final year of the Wii U or we could be seeing the NX released early next year, but whatever the case, the Wii U's death warrant has been signed; (3) We know that the NX is going to be revealed/officially announced this year; (4) We know the Wii U has been a commercial failure in terms of market penetration; (5) We have a strong reason to believe that Nintendo is banking heavily on the success of the NX. Nintendo has a lot of money in the bank, but we can be sure that another commercial failure is something Nintendo simply can't afford.
Based on those facts and those assumptions, I think that it should not surprise anyone if Nintendo makes the announcement that the next The Legend of Zelda core game will bypass the floundering Wii U in lieu of the NX, and that the delay was a strategic move to make a game that can show off the NX.
This is assuming the NX is, at least in part, a home console—of which we still aren't 100% sure. A lot of this hypothesis rests on what the NX really
is. Is it a hybrid? Is it a home console? We don't know with 100% certainty.
What I'm saying is that it wouldn't surprise me at all.
