That's potentially seven lead characters, as Professor X and Magneto have two versions each and they are, effectively, four different characters. Seven lead roles is really quite a lot and neither X2 nor First Class had that many. That's about the same amount as Avengers, which didn't have a whole host of supporting/minor characters to worry about and which still left some lead characters rather short-changed.
If this movie can pull it off, it will be one hell of a balancing act.
