Two sneak preview videos for TF: Prime have shown up on YouTube! The first is a commercial promoting both the 11/26 airing of the first two episodes and the 11/26 special Transformers-themed episode of Hubworld! We get a brief glimpse at some concept art, Peter Cullen and Frank Welker in person, and Bulkhead speaking (voiced by Kevin Michael Richardson). This ads also promotes the 11/26 debut of G.I. Joe: Renegades.

The second is a clip from from the 11/19/10 episode of Hubworld, in which they showed an extended version of a previous clip of Arcee fighting off some Eradicons. In this one, we see that the other Autobots are covering her and the humans watch from the side in awe of her combat skills.

And, in case you're interested, this episode of Hubworld also showed a preview of G.I. Joe: Renegades, which can be viewed here.
