I think the graphics difference is due to the way that the Battlefield video was recorded, as well as maybe the pre-Alpha stage (seeing as it may not have been as important to DICE as their front-line marketing, such as Thunder Run and the Fault Line trailers). It seems to use a projection-output recording system (according to my AV-consultant dad), which causes up to a 20% loss in graphical quality (or something), resulting in the pixelated look. Also, the recording of the PS3 show itself doesn't seem to be brilliant, but to be frank they look exactly the same
