Knowing ND this was probably a real time rendered cinematic from the game, using the real in-game models and the game engine.
By now we all know what ND is capable of, no doubt possible anymore.
This is the result Sony promised to its costumers 6 years ago...
Lets hope the PS4 doesn't have such a silly architecture making it impossible to develop on it.
Then whats the whole point of the message at the beginning of the video ?
"Oh look, we're streaming a pre rendered video on a PS3".
Logically, it would want to mean its real time if i'm not wrong. I don't see the point of saying its taken from an actual PS3 if its pre rendered, that would be retarded.
When the girls says "This is out routine" at 1:01, it just reminded me of how Uncharted 3 felt like a routine of doing some puzzles, killing enemies and then watching a cut-scene. I do hope this game isn't like that.
