It's the longer version - available in SD and HD - of the now well known gameplay video, but with annotations and remarks about the technical improvements over, well, almost everything else :) I quote:

"In short then? This is exciting stuff, a generational leap in video that comes at a time when Naughty Dog's competitors have still yet to match the technical accomplishments of its first PS3 title . Bearing in mind the length and breadth of both technical and gameplay marvels in the first game, we can only imagine just how good the sequel is going to be."

If you like a few technicalities or if you just can't get enough of the smooth, colorful action, jump to the Eurogamer article for the tech analysis video.

(Sorry but I could not embed it)

@BHR-3
Thanks, but that's misleading because the video you embedded is not the annotated version, but the "raw" one :) Follow the link and see for yourself.

i know i was unsuccessful to get the 1 in ur link on  but its the closest i could find

I want to see this, but I gotta wait... *sigh*

@Rainbird
I admire your integrity and willpower :)

Thanks, it certainly isn't always easy
