So I think I've found fairly solid evidence that Barricade is in ROTF. Caution, spoilers from Alliance #4 below, so if you haven't read it and don't want to be spoiled, turn back. So part way through issue 4, the Autobots are hunting Cons all over the world. However, at one point, Ironhide tells Prime that Barricade got away again says he'll notify Bumblebee, who is with Sam. Here's the panel that it appears in. So I think we'll see Barricade once again hunting down Bumblebee and Sam, since this issue ends right as ROTF begins. So he's definitely alive at the start of the film. Thoughts?
