The issue is RAM people. Epic is developing some multiplayer maps that require too much RAM to run smoothly on a PS3.
The average gaming PC has 1 GB or more of main RAM and 256 MB or more of video RAM. If Epic is working on maps to those specs, they won't run very well on the PS3 which has just 256 MB of main RAM and 256 MB of video RAM.
My own PC has 4 GB of main RAM and 512 MB of video RAM so I can easily see why some maps being catered to PC's like mine just won't run on a PS3 smoothly.
