tough question, my head wants to believe that uncharted will do better in sales cause of its timing with the price drop and excellent reviews, but man dont underestimate god of war 3 i know the first two didnt sell massivly with a bigger install base, but for some reason gow3 is getting tons of attention even more so than uncharted leading up to its release, the collection was huge at my gamestop, and gow3 has 3 times as many pre orders as any other game in my store right now. i guess what im trying to say is that gow3 has a bigger consumer awareness thean uncharted had, the casual ps3 owners know about gow3 but mostly hardcore knew bout uncharted.
