Maybe in 10 years, by then there will be a few Chewie variants, maybe by different companies, but I don't think it'll happen in the next few years. Hot Toys continually mentions that this was the hardest figure they've ever had to create. If they don't see return through figure sales (which to them, will denote interest), they won't have any reason to go through all the trouble to make a variant. Especially considering that there is little to adjust. Sure his hair looks a little different in ESB and ROTJ, but essentially, he's the same (ie., no different outfits, etc.). I could see HT creating a folded up C3PO with backpack, but that would actually be more of a C3PO variant than a Chewie.
It's not like HT intentially creates bad figures. I would doubt that they would release this Chewie thinking, "it's crappy, but let's release it anyway, and we'll do a much better version next year". There is a good possibility that this is the best they could do (for various reasons) at this time.
I'm hoping, with futzing, as long as I have him somewhere on the shelf where I'm not looking at his side profile, I'll be happy with him. Fingers crossed!
