The other speculation is that the camouflage is "opened" like that in an effort to hide the rear hatch/body lines and the exit vents are just part of this. I'm guessing this is also the case with the "wing" on the rear- just a way to throw off the body lines. I'd also hope the rear hatch really isn't that flat either. Lastly, the bulges on the rear bumper and the extra hard-lines on the door are suspect of throwing off the lines of the car IMHO.
FWIW on GT5 under the camo they have vents on the hatch...
