Eh, we'll probably get a MP Bumble or somethIng before a Soundwave.

As a minor aside, what's the big deal over heaps of diecast? Didn't it make MP1 etc kinda top-heavy and hard to pose?
I'm all up for it when it serves a stability or durability purpose but die cast for the sake of die cast seems a bit pointless to me... Is it like a nostalgia thing or what?
