Well they're not going to all come this year, and I'm not going to be buying a PS4 any time soon, and I've never bought an Xbox console (the exclusives and the controller, etc., just never appealed to me). So I'll answer as far as Wii U is concerned.
My top Most Wanted Wii U Games:
1. A bad ass, huge, epic Zelda game using that TP art style we saw in that E3 tech demo.
2. A REAL, honest to god, true and GOOD sequel to Star Fox 64, with NO extra bullshit, just Star Fox.
3. Pikmin 3, which is happening, and I hope is as good as I've been waiting for it to be for years.
4. A 3D Mario game that is not like 64, Sunshine, or Galaxy, but rather is the huge, sprawling 3D representation of the Mushroom Kingdom that we as gamers can just run around and mess around in, that we've thus far never gotten. I have no problem with bite sized levels or paintings or planetoids...but what I want, is one HUGE Mushroom World, with all the lands from SMB3, maybe even Dinosaur Island and even Subcon thrown in as unlockable worlds, and just have MASSIVE areas you can explore and gradually unlock shit in, and have warp pipes around the so you can fast-travel from area to area. THAT is the Mario game I've been dreaming of for nearly two decades. And I dearly hope to someday actually see and be able to play that. No gimmicks, no extra "neat" ideas. Just Mario, in his purest essence, as he was meant to be.
5. Another Wave Race game, with mind blowing water graphics and water physics, and have the game and tracks be a lot more involved than the previous (although for their time amazing) games were.
I know that's just Nintendo franchises, but I don't even want to get into what I'd want out of 3rd parties, because so many of them (Square, Capcom, Konami) are so far from their glory days to me now, that it's sad. I also realize that most people are listing games that are actually confirmed happening and coming out, but that's fine too, because those games I listen ARE indeed what I most want to play on Wii U.
