OK troops, Nintendo is noted for cannibalising IP, why not. We've already got a Mario of Wii U but we don't have a Zelda. Why the hell not!!?Well, Shigeru Miyamoto has a lovely, plain and calm answer:
"What is the most important element of Zelda if we were to try to make a Zelda game that a lot of people can play?” So we have a number of different experiments going on, and [when] we decide that we’ve found the right one of those to really help bring Zelda to a very big audience, then we’ll be happy to announce it."
Basically, it's not ready yet. Be patient.
