Thinking about the importance of Joker/Ren being included to Smash, and it changes the game to what to expect.
It also seems from what Reggie's comments, that the characters will be new to Smash and without having any prior representation (as seen with Challenger Pack 1). If they stick to that, that changes the entire game to what we may want to think of who comes, going forward.

Going to get Smash by January hopefully, and shortly after that once things cool over; I'll get the challenge packs. As with the first fighter, it changes the game.
Speaking of, talking to
@Joe about it, and he seems like a very easy character that could be pulled off. You could even, if you will, have him act as a Shulk: with multiple Personas on-top of Arsene.
