It would be cool to see Q again. But I'd rather see guys like Gen, Guy, Oro, Sagat, and maybe someone like Batsu and Akira from Rival Schools. There's other characters I'd rather see before them too, like Adan, Cody, Rolento, Hugo, and Dudley. Seems like there should be some new Baki the Grappler like character, since Nacalli seem to be some kind of take on Pickle.
