It certainly doesn't take them long to pirate toys these days. This might have been the first TF4 toy, out in February, but within 6 months a pirated version has shown up on ebay.
It is odd to see the backpack removed though, so maybe the pirated version has improved on the Hasbro version?
Actually, they have two versions on the listing, with one having the Leader toy's accessories.... which is even less turnaround for that to be KOed.

Looking at their other items, almost all of them are KOs.
