Kind of reminds me of when they killed off Optimus Prime and tried to replace him with a hip, cool counterpart. Bucky's probably going to be just as well remembered as Ronemus Prime(I think that's what his name is? was?). You can't improve on a classic and Bucky proved that. I'm looking forward to when he's killed off again.
From a grown-up perspectve, RODimus Prime is actually a surprisingly awesome character, even if he does turn into a futuristic winnebago for some reason.
