Back in the good old days they used to put the press copies up on xbox live for download but just set the price to 999,999 MS points, until some smart arse figured out a menu glitch to download stuff without paying for it. I think they had a heart attack when they noticed about 200 copies of Halo 3 had been downloaded overnight.
