At this point it would be speculation. Without 3D World there was basically nothing to buy other than WW HD, Wii Sports Club (which is only from the Eshop), Wii Fit U (only Eshop I belive). Talking about popular franchises here, stuff like Monster Hunter and Pikmin don't really sell that well.

Good point.  This might be a slow recovery for Nintendo with multiple game releases and a declining price over the next two years.  At least, I hope they recover.

With a strong game library and lower price, not sure what more people want.  

The point of 3D World was to move consoles, not to please fans. Galaxy 3/Universe/64-2 point is to please the fanbse.

Now that Wii U has officially failed, they can move on pleasing the fanbase. Maybe software sales are better. HW is dead now and will be no matter what game they release.

Saying "dead and not coming back" is likely definable as trolling. Be cautious.

Wii U sales are a troll at itself. But I'll be cautious.

if I read and recall the report corrcectly the wii-u numbers went from 450k-ish sold to 2.8mill for the year. Now you could argue that it's just the holiday effect, but personally I feel the wii-u would've been in real trouble had 3dworld not released. Maybe closer to sub 1mill sales for the year. Anyone thinking 3dworld would have made the console hit the 9mill mark had their expectations waaaay to high in my opinion.

Of course it's not exclusive. In this case it was a many were expecting a sequel to Galaxy's Wii.

And there's no game that will lift Wii U, unless it's something entirely new and unprecedent. I'm still waiting for the NFC games.

What a surely buy?

A New Metroid. A new Retro IP, mostly a space RPG a la Mass Effect. A new IP from the Zelda team in the line of Zelda but with ideas that don't fit as futuristic items and worlds. A real 2D Mario platformer that uses other artstyle/presentation. A Pokemon red remake on Wii U.

3D Mario World, as awesome as it is, is still the inferior game to the classic 2D Mario game, NSMB U. That is why the latter was able to push Wii U's during launch, and the former barely was, even when the price was cheaper (and yes, it DID move the hardware as it was pretty much the only Wii U game worth getting, and without it, Wii U probably would have sold far worse than it did).. The 3D Mario series, is a more "core" franchise, and thus won't be able to push much Nintendo hardware. Hell, even Mario Galaxy didn't move many Wiis.

It´s not as expensive as it looks.

Firstly, the new Metroid. It can use the same engine as Other M, just fix the problems with the game (story, linearity, voice actors). It's a second oportunity with the same assests.

Retro's Mass Effect doesn't need to have the same presentation. If the gameplay is good it will cover the part of the game itself. But, they can aslo do a Zelda Spin-off starring Sheik in the Ocarina of Time world.

Futuristic Zelda, well. I'm pretty sure at this point the team has a lot of artwork and draws that can help. And it can share the same engine as the Zelda game.

Pokemon Red Remake. The game is already done in the sense of story, gameplay and music. It will be costly, but not as expensive as for example Skyward Sword.

None of the projects I said needs more than 2-3 years of development and can sell more than games like Pikmin or WWHD.
