Will Optimus play a major role or a supporting role?

I am wondering since Optimus is off wandering around the cosmos for information about the 'Creators', do you think that he will be a prominent character or the other Autobots will have more time on screen. I'm hoping for the latter and from what I have heard, the Dinobots will be back but won't have many lines, which is kind of a bummer since they have such great lines from the shows. We've seen Optimus shine pretty much for four major movies and Bumblebee is a mostly fleshed-out character, but the other guys (Drift, Hound, and Crosshairs) I want to know more about and get some development in this film. Also, I want some development and scenes for the Decepticons other than just action scenes.
