How likely is in your opinion a Zelda U port on the next Nintendo home console ?

This might be the most expensive game in Nintendo's history. HD, large game scope, 4+ year dev cycle ... they're not going to let it rot on the Wii U where it will sell 2.5-3 million and then fizzle out.

It will easily double those sales if its in the NX launch window. There's not really much to contemplate here. 

It's also likely that Nintendo will recycle other Wii U games to push the NX. The Wii U's userbase is so low that introducing these games as 'new' to the handheld audience could recupe a lot of costs and expand the software for the NX easier.
