Seeing as how this will be a party game, I would not be surprised if they reached 50 or so. There's going to be roughly 60 characters in the console versions of Tekken Tag Tournament 2 and that game requires much larger disc space for characters, not to mention the painstaking time to balance them all.
24 characters. 16 starting characters and 8 unlockable ones.
