I know sorry I've just been dying for an answer, I guess I couldn't help but trying to ask one more time.
Sorry, but you are going to have to wait 3 more months to find out. Fine details like that are rarely known and even if they are, those people have vowed to not say another word about the project. So wait that short period of time and focus your mind on some other project OR, enjoy what you can see. I know I do and I am the bastard of details on this site.
