I hope something gets revealed at TGS, but I'm going to try my best to keep expectations low, and assumptions on a similar level, if that's alright... BUT that's just me
If anything, all I care about for character reveals is that they're unique. As much as some don't like clones, and this end sees them as... well... a bit of an, and this is a relative term, but "easy" way out of putting in a unique CHARACTER but cheating in how they would go down, I honestly don't mind who makes it in as long as they put thought and effort into it. I know the team can do it. As much as some people may not adore Brawl, I can safely say for this end that they've DONE it 3 times now; all the Smash Bros. games just keep getting better and better in their own ways.
