After Zelda Wii U, they're not gonna waist any time and begin planning Zelda NX. And if the Twilight Princess remake does come out for Wii U, I think we can also expect a Skyward Sword remake for NX somewhere down the road before Zelda NX comes out, mid to late console life span.
And that's all I can comfortably predict right now. Any other spin offs or remakes, they'll happen if they do, and if they don't, they don't.
