So I was thinking about Bruticus, the variability of the colors, and other issues people are having with it. I am trying my hardest to be optimistic so hasbro can maybe make MORE combiners, so here are my theories: Colors: We have seen G1 and Rainbow barf color schemes for Bruticus. I am ALMOST positive that the G2 color barf is a variant color scheme. One theory might be that the G1 color scheme comes in different boxes, each bots sold separately, but the G2 rainbow thing is a box set that comes with all of them for a slightly smaller price. Or maybe the other way around. Who knows. Why is Bruticus' back hollow? There will be some sort of cannon to go onto the back. It may be the reason that the back of Onslaught's vehicle mode is so blank. That might be for a cannon that goes on Bruticus' back. So, yeah! My theories are probably wrong, but it's good to be optimistic.
