With many publishers abandoning the 2009 holiday season, Uncharted may actually have less competition compared to user base then Drakes Fortune. I think that Uncharted will sell between 2.5 - 3 million lifetime. As others have already stated, there was little replayability in the original Uncharted. It probably lost many sales to rentals and the used game market.
Very few games can sell 1 million, so 2 million at a low end estimate isn't exactly a flop.
Thanks for the input, Jeff.
