My bad guess I didn't go back far enough to find it, as for proof it was because of the 360 let me spell it out for you
IT WAS WORKING ON THE PS3 VERSION ALREADY AND THEY SAID THEY CUT IT FOR SPACE REASONS, THE PS3 VERSION IS ON ONE DISK AND STILL HAS OVER 10 GIGS TO SPARE WITH LESS COMPRESSION THEN THE 360 ONE
honestly theres no reason for it to be cut out of the ps3 one except to make it the same as the 360 one if thats not good enough for you theres no helping you
