I'd say that's debatable. Dreamcast had a lot of fighters ported to other consoles, OG Xbox got similar port collections that the PS2 had. Main exclusives on PS2 were Virtua Fighter and Tekken. Gamecube got royally fucked out of fighting games, trying to make a fighter based on that controller would be a nightmare.
Last gen the 360 and PS3 pretty much share the same pool of fighters, along with any ports getting released on both and now on Steam.
