Wolf
He's almost in the exact same situation as Lucas was before his announced return. He has a trophy, he's a veteran, he's a semi-clone, he's wanted by the community, he's not a lot of work to remake.
The main differences are that
1. There's already Falco who is also a semi-clone of Fox. Falco is more similar to Fox than Wolf is, actually. Wolf has quite similar specials, but almost no other moves in common with Fox, so he's more comparable to Luigi than even to Falco. That is, It's more like bringing back Luigi than Dr. Mario. Ness is the only Earthbound character aside from Lucas, and again, Lucas mainly just shares the specials.
2. Star Fox is a bigger series than Earthbound.
3. Star Fox is getting a new game soon, Earthbound is not.
4. My impression is that Sakurai is a bigger fan of Earthbound than Star Fox.
5. Krystal might be competition for Wolf? I don't think this is a big factor.
All in all, I would've said that Wolf's and Lucas's chances were very similar before, and knowing there will be several more DLC characters, Wolf seems very, very likely.
Compare to the other remaining veterans...
1. Pichu - very clonish, irrelevant, not particularly wanted, series already has large roster
2. Roy - not very relevant anymore, was very clonish, but fan favorite. Series already has a large roster for its size
3. Young Link - superseded by Toon Link, not wanted
4. Pokemon Trainer - fundamental mechanic removed
5 & 6. Ivysaur & Squirtle - not as popular independently, don't make as much sense without being the starter trio, series already has a large roster
7. Snake - 3rd-party with a shaky relationship
It seems Roy is coming back, but I would've pegged Wolf as the highest likelihood veteran along with Lucas after Mewtwo's announcement. He doesn't have any glaring flaws. Honestly, I'll be annoyed if Roy comes back and not Wolf, given that we already have three sword-using FE characters and I didn't think FE needed four characters in the first place. Especially if he's still a clone of Marth!
Wolf chances: 85%
Wolf want: 95%
Wolf was one of my favorites to play as in Brawl. While I'd prefer if both he and Falco were even more separated from Fox, realistically, he's really not that clonish. I don't really have any reason not to want him to come back, other than I might like some other characters a little bit more (if it was any of the ones in my signature vs. Wolf...).
Shovel Knight Prediction:
chance - 42%
I think it's going to be higher than warranted.
want - 73%
But people would be pretty happy with it. At least Americans would be. If we get some of the other characters I want as well, I'd certainly be cool with it.
Nominations:
Simon Belmont x5
I think he'd be so cool, yet, so many obstacles in his way...
