Lets hope there are not as many robots in TF3. TF2 proved that shoving as many as possible into a movie ends up with next to no characterization of them. Besides Skids/Mudflap/Fallen, I can't think of any that had any character development. 1 or 2 lines doens't quite let us get to know a character (Sideswipe/Soundwave). What would be best is a small cast of robots but spend a decent amount of time on them so we get to know them. Have conversations between the robots, not just mostly human & robot conversations.
