Transformer prime grimlock

I was reading my new comic book and I flipped the page and there it was transformers prime grim lock. On the bottom of the page it says "They were there when Cybertron fell-but what happened to the dinobots for the past few thousand years? Here's a hint-grimlock and company haven't been sitting around and relaxing! The time is now-the place is Cybertron-and the recipe is action!" So I guess the dinobots will soon be in beast hunters to kick some predacon but!
