Come on guys, of all the Autobots, Bumblebee has suffered the most from Megatron on a personal level. No one deserved the kill more than him. Having his voicebox ripped out, being possessed, watching Raf almost die because of a Dark Energon blast from Megatron, and of course, just taking three fatal blows from Megatron himself, only being alive now because he landed in restorative cybermatter. Who else can say Megatron personally wronged them so? Hot Ro- I mean Smokescreen will probably get his "next Prime" moment in the movie against Spoiler Galvatron.
