It probably wont happen. I am well aware that Transformers is a franchise and that Hasbro has to sell toys and all, but do we really need more Autobots in TF5? I mean we have 5 autobots that for sure survived tf4, and 4 Dinobots. Pretending that Optimus is not in TF5 (which I doubt), we would still have a cast of 8. Now I'd love to see various characters on the big screen, but Id rather continue the character development of these 9 bots then adding more to the script (which reduces ea. Of the bots possible screen time). I rather them take the Prime/Animated approach and keep the team small and familiar over the next 2 movies. So yeah, this is my responce to all the "I want this and that autobot in TF5" threads.
