This is most likely photoshoped, but the rumor was from Bigg_Gunz on LS1TECH. According to gminsidenews, that guy is legit.

"-Have I seen the next generation camaro?"
"-Yes I have and it looks billion times better than the current camaro. (which I am not a fan of the looks or plus size model like weight)"
Going off by that, I would guess that the 6th Gen Camaro will no longer be the "big" car many of us like. Who knows if it will continue to have the retro look.
