Horror Games. But like Resident Evil's chances are dead anyway due to the spirit event, and I don't think we'd get a Silent Hill character.
As for the whole "we can get multiple reps of a genre" thing I do agree with that. If we get Crash, Rayman would likely be next. There are other platforming reps we could get but they each have their own problems.
Spyro - Something from Spyro could come with Crash Bandicoot, and the series is even less popular in Japan than Rayman is because they messed up the localization for Japanese Audiences.
Gex - Heavily successful franchise, but suffers from too much competition within Square Enix. I can't see Gex getting in over Lara Croft, Geno, Sora (That's effectively Disney but they still have to go through Square), 2B, Neku and even Chrono.
Another Sonic rep - Very good chances on this, but suffers from competition with Arle or the slim chance of Sakura happening.
