"Save" is too subjective.
There's likely enough in the pipeline (combined with currently released titles) to satisfy gamers who have either already purchased the Wii U, were on the fence about getting one, or will purchase the Wii U down the road. The quality titles are there with more on the way. Unfortunately, third party titles are always going to be swimming against the current here.
Against the PS4 & Xbox One, the Wii U is a tough sell and the lack of support doesn't help either. If a title looks and performs significantly better on a rival system, then I'm unlikely to purchase it for Wii U.
I think the Wii U's potential lies within its familiar franchises, first party titles, and its exclusives.
As long as Nintendo keeps that in mind, I think it'll do okay.
Gosh though, it's so strange seeing people compare the Wii U to the Gamecube. I guess it's more of a "units sold" kind of comparison but still. I think the Wii U's best days are still ahead of it, but compared to my GC, I've barely touched it at all outside of Mario 3D World & Mario Kart (and I've had it since launch).
The GC though, damn, I played the living crap out of that system, from the very beginning. I played it more than my PS2 during that gen, and I got both of them at launch. Games like Melee, Wind Waker, Sunshine, SA2B/DX, Kirby Air Ride, Animal Crossing, Symphonia, TTYD, to name some of my favorites off the top of my head. Definitely rivaled my N64 gaming days.
I'm sure we'll get even more great games for the Wii U too, but I don't know if it'll rival my GC/N64 experiences.
