I'll answer this, lol.
Right after the movie was shown in theatres, they same people who made the prequel comics for the movie, they decided to make somewhat of a sequel comic, and possibly three others to continue where the first movie left off since the sequel movie itself might take place a year or two years later.
The first one will be The Search for Starscream, which is weird since none of the Autobots can fly, but maybe they make a base or something.
I HOPE one of them will discuss about Barricade and where he fled.
AND, if it's already made; I heard once that the comic will come with the movie and in only Best Buy stores.
