I don't really think GoW 3 deserves twice the sales it has right now, because even though it's an awesome game with some of the best graphics and scales, it doesn't have any form of multiplayer or co-op. Now I'm not saying it needs these features because the developers might have decided these features don't suit it well. After the amazing experience is over, there isn't much else to do for the game. I mean you could play the story a couple more times and do the challenges, but you're not gonna get any kind of prolonged use).
Now a game that DOES deserve twice its sales imo is Uncharted 2. It has an amazingly colorful campaign full of lifelike characters and a very nice plot based story. It has a really good multiplayer component with a lot of interesting game modes and it also has co-op. I'm pretty sure Uncharted 3 will build on all of these factors whenever it comes out.
