Im starting to think Nintendo will wait to see what Smash does for the system, and if they're not satisfied with the results in 6mos, I think they will "delay" Zelda and have it ready for the next gen Fusion (lmultiple hw types & same game = no more "double dipping").
Nintendo is in the business of selling lots of games, and you need a big install base to really profit (i.e. NSMB wii and MKWii). Nintendo was on record as not happy with gamecube and even called it a failure. They can't afford to waste efforts on a system no one cares for. I am betting on the next Zelda becoming a multiplat.
Nintendo is at a very low point right now, humiliated and lapped by the competition despite being available on the market for a year longer. PS4 is about to double Wii u soon in ltd. So the bottom line is Nintendo and major 3rd parties are done, and they have to support themselves to boast a rich/diverse game library, under a unified system. What throws a wrench in this plan is the new 3DS, which extends the life of that console. But I think there's a decent chance of an announcement at E3 '16 for a winter '16 release of the Fusion HH. Home console or FusioNES will be made avail. in spring '17.
