To be fair, I think the game lineup on all three consoles is very lackluster and would go as far as to say that next gen has simply sucked so far.
I have no interest in any of the games for the 360, PS3 or Wii that you mentioned above.
Out of announced and released games for the consoles thus far I have an extreme "must buy" type of interest in:
Wii: Zelda, Super Paper Mario, Metroid Prime 3, Mario Galaxy, Smash Brothers Brawl (if it has online play), Mario Kart (if no snaking)
360: Oblivion, Gears of War, Halo 3, Mass Effect, Bioshock, The Darkness, Forza 2
PS3: Final Fantasy XIII games, Ratchet and Clank
I just listed exclusives, and didn't bother with multiplatform titles. Not much exciting me their either other than the usual sports titles (which I'd skip on the Wii as HD graphics are key in sports sims) and Guitar Hero 3 (which I'll get on the PS2 since I already have 2 controllers).
As you can see, I agree that it is slim pickings across the board. The Wii just gets more complaints from me as it was the one I foolishly decided to early adopt rather than just giving this gen 2-3 years to get game libraries built up and have some price drops. It's no worse off than the others, but I do feel it has less potential for me personally as I didn't end up digging motion controls like I thought I would and the aforementioned lack of HD sucks now that I have an HDTV (which I didn't have when I bought the Wii).
At least I learned my lesson finally and will never be a launch buyer of any consoles in the future. Just not worth paying the premium to sit out these game droughts, not to mention you make much less informed decisions about which ones to buy than you can a couple years down the road when more games are out.
At any rate, the point is that I'm not anti-Nintendo, or even anti-Wii. I'm just a vocal gamer that is hugely let down by next-gen thus far, and the Wii gets most of my bitching as it's the only one of the 3 I have right now.
That said, I've been a huge Nintendo fan since the NES and the Wii will definitely get a lot of play this fall with Metroid, Mario and Smash Bros (if it's online).
I'm a bit extra bitter as the controller has a lot of potential for coming up with new franchises for gamers, and not just new franchises for non-gamers like Wii Sports/Wii Fit and Nintendo has yet to give us any indication that any new franchises for us lifelong Nintendo fans.
They are doing a great job getting sequels to to the big franchises out (Zelda, Mario, Metroid, Smash Bros, Mario Kart etc. in the first 18 months is great), but with those and all the spinoffs that I hate (Mario sports, Mario Party etc.) and the non gamer stuff (brain age, wii fit etc.) it's hard to see them devoting much attention to coming up with cool new games/franchises for the hard core gamer.
Maybe they'll prove me wrong, but I don't have high hopes as the DS hasn't really saw any "new" games for the hardcore from Nintendo. Third parties have filled that void, and it likely will be up to them to do the same on the Wii IMO.
