There is a point to this. Yes we would all love every game to be 60fps fixed, but better graphics sell a game moreso than better framerate. If you look at Killzone 2, Uncharted, Uncharted 2 and MGS4, they were all 30fps max but have the best graphics of this generation so far (on the PS3, so to stop a flamewar).
I'm not sure what R2 had for a framerate, doubt it was much more than 30fps at times, but R&C is 60fps and really isn't required, especially if you can push the hardware that little bit more in the graphics department.
Thats not to say that R&C looks bad, it looks great, but it seems that developers apart from the PD's of this world with car sims really need 60fps and maybe your Tekkens and Soul Calibers, but every other genre really only needs a fixed 30fps or as close to that as possible.
It means that developers like Insomniac can say straight off 720p @ 30fps and then dedicate everything else on the upping the quality of the visuals as long as they adhere to the res and framerate.
