Okay, so let's just ignore all the credible reviews and condemn the game for being repetitive....
There are no loading times in this game:

"You can play the entire game without loading. We don't require an install. We're doing all the post-processing effects on the SPUs [Synergistic Processing Units]. The quality of the depth of field we have, you can't do that on the Xbox."
You can ignore the stuff about you can't do it on the Xbox, which whilst being true is not relevant, the main point is they are wrong basically. They might be referring to if you start a chapter from the menu, then you get a bit of loading
