Certainly Gears1 had holiday shopping season for boost and that could contribute to the reason for the higher first week sales.
However, I just don't understand how the current smaller user base for PS3 could be used as a reason as well as how people comparing Killzone 2 to Gears1 is unfair cause it's an established franchise. It was a new IP when Gears 1 was released.
This is a slow time of the year and Killzone 2 had a good first week. It might not be record breaking but it's decent enough.
MikeB predicts that the PS3 will sell about 140 million units by the end of 2016 and triple the amount of 360s in the long run.
