Keep in mind that it was Chewbacca we see in the trailer, who looks very much like the Wookie that's in every other picture we've seen.
I'm really laughing at all of this because had their been an internet back then people would have been complaining the Chewie in 1980 ESB looked too different than the one in ANH, and ROTJ. Same goes for ROTJ as compared to those first two. You cannot clearly see Chewbacca's eyes in every scene he's in of the OT either.
