Atlus has updated the US website for KOFXIII with some of updates the Japanese website received yesterday, it's not quite as up to date but for now you can check out Saiki and Flame Iori's move lists.
You can check that out here.
I also got an e-mail from their mailing list regarding the pre-order bonus CD, which i'm hoping will make it's way to the UK also. If not i'll probably ask my cousin to help me import it...
[Edit]: Just got my cousin to preorder me the PS3 version from GameStop in the US, roll on October \o/
