1600x900 resolution? With like 50xAA? That isn't a bullshot? That's probably around seven times the resolution the game will really run at and maybe 50 times the AA the game will really have.
I doubt the "1600x900" is the native resolution, but if it helps the first screen is well under that and realistic. I don't know where you get the 50xAA from, a source would be nice. Regardless of what tampering there may have been with the screens, there isn't a noticeable difference from the gameplay videos shown other than being of higher image quality.
