Cool thanks, but in some moments it seems the game hiccups in that HD video, I'm sure they hurried up with the release, PS3 needs it now like never before. So they didn't have the time to optimise it perfectly. That's in case I'm not mistaken with the sources of those hiccups in the first place. I also have noticed some slowdowns in this beautiful french demonstration while during replay section by the end of thye video. Nevertheless the resolution is amazingly high even for a modern high-end PC videocard(1080p) and seeing such high quality graphics+HDR @60fps is one brilliant achievment, I'd say most brilliant thus far on PS3.

edit: the video slowed down, not GT. I just reloaded the page and the video is smooth now.
