Its pretty simple the 360 and PC hold the same architecture since the biggest platform for this game is the PC and 360, they developed the game for the PC+360 and are porting it over to the PS3.
The issue with ports is you are taking the weakness of the 360+pc version and adding the PS3 which inherently makes it worse. As people have mentioned if you drop it months later you can re write a lot of code to fix most of the issues.
This is going to be a common theme with most muti plat games because the PC/360 market is going to be bigger than the PS3 for the next couple of years.
Last gen PS2 was the dominate platform so all games were developed for that and ported to the other players, this is the advantage you get for having a bigger user base. Plus the 360 gets to add PC people to there numbers.
But seriously if you own a PS3 only your getting a great game still
PS3, WII and 360 all great systems depends on what type of console player you are.
