I could be wrong, but I don't think they have, and that might be part of what's creating the backlash. If they would say outright, "this is a party fighter", I think people would be more accepting of what they're trying to do here (there's no excusing that sort of retail exclusive DLC, but you know what I mean) rather than trying to analyze how balance is supposed to fit into all these subsystems.
Might lose a few sales from people looking for more serious, competitive fighting games, but this game is already looking like a big joke. Might as well come out with it.
