Mystery solved! The yellow robot from the movie moon trailer turned out to be Sentinel Prime after all. A new article from Entertainment Weekly give us a ton of information regarding the crashed ship on the moon, which turns out to be the Ark after all.
I really am not excited that these characters that are more recent additions to the fiction are becoming so important. The Fallen was not important enough to be in the last movie, and now we have the defunct Dreamwave Production’s Sentinel Prime becoming a prominent figure in the final Transformers film. Plus they’re gonna kill Starscream… at least the latest trailer looks promising. Countdown to July!
