Hasbro had said that they didn't want Megs transforming into a gun b/c they wouldn't market a toy like that, which makes sense. Megatrons transformation is beyond weak. He's the big, bad ass leader of the decepticons, turns into a super powerful weapon, but someone else has to use him in his alt mode to shoot him? It's like Darth Vader turning into a lightsaber and then someone else having to wield the weapon. (My favorite metaphor with this entire discussion). Thankfully Galvatron gets a better alt mode, but who came up with that idea for Megs in the first place?
Back to the topic discussion.... just because the All Spark was mostly destroyed that doesn't mean it's not a plot device. And if the All Spark is suppose to be this all powerful, even and objectified "God-like" artifact to the Transformers, then maybe even only a piece has some type of power. Even if it didn't have any power it could still be used as a type of symbol for hope. The whole idea that if there is even a piece of the All Spark then maybe they can save their world? :p I dunno. I'm just throwing out random ideas here.
