I have it being around 35 characters. I'm hopeful for Gappy Josuke but I won't be surprised if he doesn't make it.
I was thinking about Soft & Wet and maybe it could take away peoples buttons, for example, say it was 236A for a bubble, it hits then it takes away the opponents use of A until the bubble pops/Josuke is hit.
Also there's going to be lots of OraOra type stands, I hope that doesn't make the game seem stale and too uniformed if you get what I mean
