I think we can expect more and more sales for all PS3 exclusives (be it former, or upcomming). PS3 Slim was a very important step in the PS3 life cycle, due to the price, more and more people will buy it and of those people, there will be a decent number of gamers, which will ofcourse reach for the best games out on that system. I myself have quiete a lot of friends and internet "buddies" from my country, that were either waiting for PS3 price drop, or a particular game (GoW3, GT5, Trico), they all want to play MGS4 and they will eventualy get it, but they are waiting for more. So if someone like that will buy a PS3, he'll want to play Uncharted 2 > he'll get the first one to know the story and so on... Many games and specialy such a quality titles like MGS4 will have strong legs into the future.
As for MGS4 numbers, I don't think they are very accurate on VGChartz I bet my left testicle on the fact that MGS4 sold MORE units in Others than NA.
MY HYPE LIST: 1) Gran Turismo 5; 2) Civilization V; 3) Starcraft II; 4) The Last Guardian; 5) Metal Gear Solid: Rising
