Barricade was originally voiced by Jess Harnell in TF1, and I thought the voice was perfect. Then Barricade returned in Dark of the Moon, but was voiced Frank Welker. The line, "Your time is up!", lead many to believe that Soundwave killed Que/Wheeljack, as Welker voiced Soundwave. Considering Ironhide was turned to a pile of worthless scrap, I think it would be fair for Harnell to have another role in the film, obviously as Barricade.
