That's a bit late, but probably because of the economic climate. At last year's toyfare in April, one of the licensed toy car distributors was saying that the Camaro was supposed to be coming here by the end of last year, which is why you can find a lot of the Bumblebee coloured Camaro toys in toystores (they were cashing in on the TFs movie, without actually having to pay any royalties).
I'd expect a Bumblebee coloured one though, at least by the release of TF2. Or there would probably be a few people custom painting theirs.
