Already? Come on the game was just announced. Settle down haha.
What I can say, is that thanks to Uncharted 2, the series is regarded now as a premiere franchise that is one of the best in the industry. So this could really rally up more first week support compared to that of Uncharted 2. Also, based on the sales over time, it does seem the mainstream gamers recognize it as a prominent Playstation franchise. So this really has a chance to be a much bigger seller than previous ones in the series.
I think some factors that will determine sales will be status of the multiplayer. If they can really get a game that comes off as a premiere PS3 only multiplayer title, similar to that of Gears on 360, then they could have a big hit. Especially if that multiplayer includes split screen and cooperative play.
