The differences seen in just the TFA stuff so far seem to point towards another Wookiee being in the film, most likely Chewie's kid.
I'm inclined to agree... I'm just wondering how they've kept this from leaking out. Then again, we haven't seen much of Hamill, aside from the teaser.
That promo art seems to show a different Wookiee, too.
