I'm pretty sure the only non-canon/retcon element of the Red Trailer is the Beowolves, which got updated to the final Grimm asthetic. It's like a game in its Beta, or more like Alpha stage, where it's very much early in development and stuff changes for the "final" version. In this case, the Beowolf model. Ruby was updated a bit too, wasn't she?

The other three trailers all look to be the exact same models and such as the rest of Volume 1.
