While i very much doubt that they deliberatly held back the PS3 version a bit, i wouldn't be surprised if it didn't fully/efficiently use the PS3 architecture as much as it did the 360. The 360 is easier and cheaper to programme for, end of, the PS3 may well be capable of more but i think we'll need more time for developers to become comfortable with it and they'll need more money too.
I very much doubt we'll see what the full capability of the PS3 is for a couple of years yet, Sony have shot themselves in the foot a bit by forcing such an unfamiliar device onto programmers without supplying them with devkits early enough for them to familiarize themselves. I also believe the 360 hasn't seen the end of its capabilities yet, but due to the familiar architecture and coding language i would be willing to bet it is closer to its maximum capabilities than the PS3. I don't think the difference will be very big by any means, but the amount games like Uncharted and Resistance visibly improve as you progress indicates that it is a slow learning curve when programming for it whereas games on the 360 were visibly stunning from the very beginning. While uncharted started behind Gears graphically, i feel by the end it had surpassed it for example.
This isn't a bad thing for microsoft however, i'm sure they have the xbox720 just waiting to be rolled out.
