Let's give this one more try.
The PS3 version is identical to 360. Same textures, same visual effects, same pop-in distance for LOD. Framerate might actually be different between the two platforms under certain circumstances, given how they're entirely different hardware. I played through both console versions more than once - framerate is consistent throughout and won't be a problem at all (unless you can somehow tell when the game is running at 24 vs 30 FPS, and you find 24 frames a second unplayable. If that's the case I would expect you to have issues with many games, not just Dragon Age).
The game delaying for the PS3 in various regions has to do with certification/publishing differences in those regions, and absolutely nothing to do with the development of the PS3 version.
I'd suggest you wait until you see for yourself, or until more comparison reviews come out, before you draw final conclusions.
