it would be very difficult to get or destroy the molds from China. the Chinese government, while signing on to international IP laws, do not enforce intellectual property laws with any kind of consistency. granted this was 15 years ago, but DVD bootlegging was so rampant i'd get bootleg DVDs of their films to give to my obscure indie filmmaker friends. EVERYTHING had been knocked off. thus i think the "destroy the molds" scenario highly unlikely, at least for the kits produced in China.
Korea is a different story.
also the movie biz don't destroy *everything*.. Tom's Diner (the one in Seinfeld) is still up near Columbia University in Manhattan :p
