I think they'd make a console exclusive game designed for consoles. Their current lineup of games are far to fast paced to be properly played on a console (except for maybe the wii). I truly think they'd design something thats catered specifically for the format and not port one of their pc games. They did that in the past and it wasn't very successful. I doubt they'll take that road again. Whether said games use an existing ip or a new one is anyones guess.
I'd be excited to see the results.
