doubt it, Guy is basically confirmed, and his partner is Cody. No point in adding Maki as well as Guy.
I'd like to ask a question to everyone here, many times when creating rivals or teams, we get similar characters, would you like to see that team or rivalry even though you get similar characters or would you prefer a more diverse roster but it sacrifices good teams and rivalries.
Examples
Fei Long VS Law, you end up with 2 bruce lee wannabes
Elena vs Christie, 2 capori fighters, probably even have similar looking moves
Honda vs Ganryu, 2 sumo wrestlers
Kazuya/Jin, don't know much about Tekken but isn't Jin similar to Kazuya
Sakura/Karin, Karin is okay, but would we need another shot like Sakura
Sakura, Karin, Lili, Asuka, Ling, how many school girls is too many
Zangief vs Kuma, this rivalry makes too much sense, but do we need another grappler like Zangief when we already have so many wrestlers
