FT86 concept vs production

Toyota FT-86 concept vs production car. What do you think the production version of FT86 will lose? Probably all of the carbon pieces (on wheels, diffuser,mirrors, etc). I dont think the diffuser will go away, probably it stays, but material will be plastic. Interior should change drastically, its too sci-fi currently and the zippers won't make it to production, unless there is huge testing and debate about zipper interior usefulness during these next ~700 development days. Of course this is just a speculation/rumor topic. As always we can polish the fact that Toyota is listening and will probably adjust the part stripping according to public needs :D
