Every MK characters on the MK guest poll were in MKX. Scorpion's Injustice moveset was largely rehashed from MK9, his supermove being his only new move. Does that mean that the same thing will be done with any of the other MK guests?

Personally, I hope not. I also hope that doesn't mean any MK guests in future non-MK fighting games from NRS can only be characters from a MK game that came before them.
