I'll argue it - FoC Rumble is Aligned, not G1. That is Hasbro's official position. As is Prime Rumble. All blue Rumbles that have actually been released at retail by Hasbro have been non-G1. Hasbro has never released a blue G1 Rumble at retail. The only official blue G1 Rumble toy by Hasbro is that Kre-on, which was a convention exclusive.
