Let's not lose the original question (we could nitpick about the budgets required for AAA, AA, etc)...
The OP is asking whether Zelda will be the final big Nintendo title to hit Wii U.
Itwata and Reggie have stated many times that they are committed to Wii U owners and if history shows anything they usually make good on these types of promises even when it comes to their own detriment. Many of the other posters even stated that it doesn't cost nearly as much for Nintendo to develop one of their big titles as it does your Ubisofts/EA's of the world. They will be able to keep costs down which ultimately is one of the advantages of developing for your own hardware. Expect to see at least 2 big name games in 2016 and perhaps 2017 as well.
run away!
