Assuming those screenshots are real, 17 across by 3 high = 50 + Random, fill in the revealed characters that aren't there... then that means that there's 21 characters that have yet to be revealed, including the veterans that haven't been shown off yet (judging by the space between DeDeDe and Fox, Meta Knight is pretty much a given, for example).
