I highly doubt Wolf will be cut, because A) he's a villain rep, and it's hard to get playable villains into the series, (Bowser, Ganondorf, and Wolf are it, Dedede doesn't count because he's often a good guy so more of an "anti-hero,) and B) he's a more important Star Fox rep than Falco, who I think would be more likely to drop than Wolf. But if you really want to know who I think will be cut, here they are, from most likely to least:
- Lucario
- Snake
- Ike
- Toon Link
I don't WANT to see any of these go; matter of fact, I like all of them, but these are the ones I feel most likely. I really don't see any reason for PT to go, and Olimar is still the most important character in the Pikmin franchise, (he will be in all 3 games, as shown by Pikmin 3's Bingo Battle Mode; the fact that he's the second player instead of Brittany suggests to me that he may be somewhat important in the main story as well.)
