This is more incredible when you look into it. AA is rather complex. Uncharted 2 for example is 2xMSAA. However it has no AA on shadows or effects. Makes it more impressive that Alan Wake is 4xMSAA even on foliage as well as shadows. Finally people are putting the EDRam Chip on 360 to use. ( 500mhz clock speed with the equivalant of DDR3 64 mb, thats how fast 10mb EDRam is. )
