Well, I got to gamestop to try to exchange, they got like 2 black and 3 red on the front shelf, I took a peek at the red one and it is XX1 and i exchange it with mine right away. I noticed the 2 black they have are XX4 as well. Went home check the red and the firmware is 9.0. BTW, I noticed something very weird, the first black I got from the gamestop doesn't have those security sticker on it and the red i just got have 2 of those security sticker on both end of the box.
