The cutscenes and the new games even in consoles using normal maps but if you see that effect you can see in the borders the low polys and in the fill the great effect appear to be more poligons

And I have to many games (how gear of wars) and he using in any scenes videos, in ps3 I don't know but I not see nothing from that console, but in xbox360 is very easy to see when are videos, all the models in screen have a high antialias filter, but the realtime only use x4 and not in all the models

The programmer try to make the video near to the realtime graphics, but not all the scenes are in realtime, why the game not are the same in cut scenes(deep in scenary and the full amount of scenary models) and a play game

I think also the ps3 use the same technique if not why a game goes to use a 20gigas or 50 gigas blueray
