I'm feeling that you are right chimera might be next and this seems of but I think it is maybe a demon souls character or even a lair character. If not atleast a stage from one of those.
Well it's confirmed Emmett and kat are rivals soo if chimera was released next dlc pack who would the other character (rival) be?
Now that you mention it, we'll probably be seeing all DLC characters released in pairs
ikr i think that they will be priced good, anyword on arenas?
