Looking at Arcee and Chromia... I'm having a hard time picturing them combining (unless the net result is also non-humanoid). Is it possible (or even rumored) that there might be smaller versions of them? Possibly with the ability to comine? For one thing, it turns out that only the smallest (Legends scale) versions of the Constructicons will be able to combine... maybe that's the case here, too? Also, they look really tiny in the trailer when they're chasing Sideways; certainly not as large as him, so why should the only figures of them be? I'd think Scout or even Legends size would be more appropriate, and give us a reasonable shot at a combiner.
