Two more trailers, with more new scenes...

This one is in Russian (so is a bit amusing), but shows a lot more of Bumblebee, Hound flicking his "cigar" at a human, and the Cyber-wolf pack.
Hopefully an English version comes out soon, as I want to re-watch it.

This one is filmed off a TV (so doesn't look very good), but shows us a new scene with Bumblebee in an aerial battle, and Grimlock.
