Eh, it's hard to tell for sure if they've made actual tweaks to the costume along the way since that first pic with Iger (there's different lighting, different perspectives, different expressions, and loose vs slicked back fur for each pic), but I'm pretty sure it's still intended to be Chewie in each of those images. It would be very cool, though, to see another Wookiee besides Chewie.. maybe Lumpy ;)
New interesting looking Promotional Banner for the TFA.
