it's just a matter of did nintendo/rare's agreement with the movie studio include the right to sell the game in perpetuity, meaning activision has the right to make new games but nintendo is still free to sell their old one.
*and* does nintendo or rare end up with ownership of the title. if it's rare, will they license it (why not, honestly? even if you drop it on 360w/online it's still the option to sell more games). if it's nintendo, then no biggie. if it's some sort of dual ownership, in the end rare will have to get on board or risk a court battle. or nintendo just won't give it up.
you can count on it costing at least 1500 wii points, it is going to definitely *have* to include bigger payouts to anyone who owns the rights. especially when the demand for it is this high.
