I know there's footage of Coded, but i haven't looked yet. I just haven't been paying too much attention to it. I also know about the new scans for 358/2, but there's nothing I want to say that hasn't already been said in previous Xion posts. It's still up in the air about how things will turn out. I haven't seen many problems with Xion though, so maybe she won't be Kairi, but given what she's been saying in the new scans("I want to be together with you two"), you can bet she will be. Sad, but that's what happens with female characters like her.
The new scans showed more Xemnas, Saix and Xigar. Beyond that, like I said, it's more of the usual.
