Given that Robin specifically calls for Chrom during the FS, I think it's safe to say he's probably just a Final Smash accessory at this point.
Final Smash is clearly a reference to Assists and/or Pair Up.
I didn't expect this outcome for FE: Awakening. Also didn't expect 4 reps. But I guess with it's MASSIVE success...
Also I don't like how they basically kicked everyone who wanted Chrom between the legs in the end. 'Yeah he's in the final smash. And he he's been beaten up by Falon. And he even says he might get his chance next time'.
Speaking of; they made Falon awesome. He beat Chrom. He was beating Lucinda; and he didn't seem hurt by Robin [Although he had to cancel his Falon Punch].
I'm a little dissapointed they didn't reveal him alongside Little Mac instead actually. You know... two fistfighters...
So updated character count
Now there are 11 newcomers and 25 vets, for a total of 36 characters so far. Brawl had 37 in comparison (39 if you count Pokemon Trainer as 3)
There are now 14 unconfirmed veterans: Wario, Squirtle, Ivysaur, Metaknight, Lucas, Ness, Ice Climbers, Falco, R.O.B., Game & Watch, Ganondorf, Jigglypuff, Wolf, and Snake
If they all made it back then there would be a nice round 50 characters in Smash 4 (although Squirtle, Ivysaur, and Snake are looking unlikely)
There's also Mewtwo, sakurai pls
Technically Squirtle; Ivysaur and Charizard are newcomers. Pokemon Trainer is the Vet.
I don't see Earthbound reps or the Climbers getting dropped. R.O.B might go; as with Jigglypuff. No way Ganon isn't in it. I'd hope for the Fox clones to be got rid of, or at least Wolf; and of course either Meta Knight to be gone or heavily nerfed.
Wario... he represents WarioWare as well as Mario. He's almost certainly staying.
Game and Watch could go either way. I get the feeling he might be gone.
Snake is probobly gone. I don't think Nintendo is working with the MGS team anymore. Might be wrong.
Inb4 replaced with Raiden
