Yeah like other people said MGS3 released during a busy christmas season against tons of competition
MGS4 was hyped alot more than MGS3 plus the PS2 had so many AAA games, whilst the PS3's picking were rather sparse before MGS4 came out which probably helped out with its sales a good amount.
MGS4 was bundled too which helped out somewhat on sales too. Not sure if MGS3 was bundled or not.
And the last reason why it sold more was because its just that good of a game.
But remember bigger userbase generally means more copies sold of any given game....
