I think Dan is very unlikely because you have to get people to actually pay money for him.Assuming we know the 6 DLC characters from mining the beta who would you think would be the next set of characters? My guesses are Akuma, Dan, Sakura, Blanka, and 2 new characters. Though, I wanna say Cody and Guy. This is assuming we get 6 characters a year (I think that'll change in 2017 though).
