Update: It seems THQ may be the publisher after all. Capcom USA told Joystiq this was an error in the listing. "Capcom does work with THQ Australia on a number of our titles, so this may have just been an easy mistake. We are not working on this." We're told THQ Australia is working to correct the information.
We still don't know any release date or pricing information, but ratings filings are usually a good indication of logistical specifics in our near future.
