Hehehe... I was just trying to remember where that was from, because I was going to post that Hasbro have essentially assured us that Kickback is coming, but I wasn't sure either where it was from. Definitely recent, so either NYCC or SDCC... or maybe even BotCon.

Looking again at the SDCC panel, it was only as recently as July that Hasbro were saying that the Deluxe toys would still have comics with them... so maybe the samples showing up in the last week are the non-American alternate packaging version. Or it was just a really last-minute cost-cutting measure.
