Due to disappointing Wii U sales, there's a slight possibility that we could see  smaller games (ex: Yoshi Woolly World and Captain Toad Treasure Tracker), or remastered Wii and GameCube games filling in the last years of Wii U.

Why? Because Nintendo may be saving them for their next home console's launch window.

One of the biggest mistake Nintendo made this generation was the software drought at the very start of Wii U's (and even 3DS) life. By delaying huge games that are in development now such as Fire Emblem x Shin Megami or the next anticipated 3D Mario and Metroid games (if they're being developed in the first place), Nintendo can release them for their next gen home console within its first year. Additionally, history has shown that Nintendo releases very few games for their home consoles towards the end of their life. One simply has to look at what Nintendo released in 2011-2012 for the Wii and 2005-2006 for the GameCube. In the Wii U's case, disappointing sales could lead to fewer or even no huge titles at the end of its remaining two years. That brings us back to this thread's question. How likely is Zelda U the last AAA title for Wii U?

Edit: Due to uncertanity of what Nintendo games are considered AAA, I've changed the question to be: How likely is Zelda U the last big title for Wii U?

Here is what I consider big titles: Zelda U, 3D Word, Mario Kart 8, Xenoblade: X, and Smash Bros. U.

I'm basing this off of the game developer's pedigree, the game development's size relative to past Nintendo development sizes, the game's development cycle, the game's purpose to sell home console, and the game's quality (scores near 90 on Metacritic or above).

They probably will have a metroid game yet.Plus,Do we know if Xenoblade will came first?

I don't consider any of Nintendo's games AAA, including Zelda. Keeping their spending in check is the only way they can be profitable with such a small user base.

They are very secretive about their budgets so it's difficult to be sure.

Xenoblade is coming out in Japan in April and its likely it will be localized this summer. 

But if Mario and Zelda don't move this console than why save them until next Gen. Why will the mass market respond to these games on another console.

I don't think it matters if they withhold AAA content or not. The quality of their own titles has never been an issue.

Quite unlikely. I think there is room for at least one more year`s worth of AAA games to come from Ninten, whether next year or the year after. But I doubt Zelda will be the last. ( I`m hoping SMT x FE will be one of the last ones...! : ) )

Probably not. I am sure they have a few more in the works for 2016 which we will see at e3

Yeah that's true. Nintendo doesn't spend as much money in their games compared to other studios. But for the sake of the argument let says AAA Nintendo titles are the ones that cost Nintendo the most to make as of this generation including: 3D World, Zelda U, Xenoblade X, Mario Kart 8, Smash Bros. U, and etc.

AA titles would be Yoshi Wooly World, Kirby's Rainbow Curse, and Captain Toad, and maybe the New Super Mario Bros. series

A titles and lower would be Wii Party U, Wii Fit U, etc

And lower would probably be their eshop games like NES Remix.

I'd argue Splatoon is a AA title unless it has more online multiplayer mode and the single player mode is 10 hour plus long.

This is a very interesting point, actually. If stuff like Zelda is AA (and I would agree), then stuff like their 2D platforms are generally, what, A? These are terms we don't use a lot. xD

It's probably not the last one. With all the problems is probably having, SMTxFE will be the last big WiiU title, simply because it will take a loooong time to finish.
