Come on. It's either this or never see him playable. Why be all high and mighty when we know this is BEST CASE for him? It's easy fan service.
I believe sal has leaked every character, it's coming down to which veterans aren't returning, and DLC speculation at this point.
Brawl cast -Squirtle - Ivysaur for sure
Lucas and Snake are both questionable
+ Megaman, Pac Man, Rosalina, Wii Fit Trainer, Greninja, Little Mac, Villager, Palutena, Miis, Chrom, Chorus Kids, and Shulk
This leaves us with 49 characters, assuming Snake AND Lucas come back. Now, it sounds like Lucas is cut, so that leaves us with 48. The final piece to the puzzle is Snake. Is he in? Or no?
We pretty much have the roster now guys.
DLC is what I'm aiming to speculate about at this point.
