We know by now that there will be a 4th Transformers film coming 2014. The question is will they have animal/primitive transformers in that film? I hope they do and I want Grimlock and the rest of the dinobots and the Predacons. No doubt Grimlock is very popular in the TF universe. Should they have more animal/primitive characters in the 4th TF film? If yes which characters you want to see?
