Triple post...
Terra, Bartz, Ex-Death, and Cloud were confermed at TGS today/yesterday. I don't have pictures as I'm on a school computer and my internet at home is being stupid, so once I figure out what's wrong, I'll get more info on it.
There is a picture on the Wiki article, but that's all I can find right now.
Edit: Just went to the FFwiki. Cloud has his original hair(wh00t!), Bartz has brown hair(sweet!), and Terra...has...Blonde hair!(*sobs*).
Edit 2: Lalalala...Post people post!
The whole cast's artwork! Plus three CGI pictures (Kuja(he has pink nails!!!), WoL, Squall, and Sephiroth we've seen in different pictures, but not Mateus(who looks a little creepy) or Terra(well duh! Though they did capture how she should look really well).
I'm actualy liking Blonde Terra, though Green is still better...
