According to http://kh-n.com/, it's not certain if 358/2 or Birth By Sleep will be shown. Hmmm...well, I can understand the secrecy, but doesn't common sense indicate that they WOULD be? Meh, who knows? Surprises tend to pop up pretty often in Game Shows. At least from what I've seen.
Because I know not to ever get my hopes up, I won't, but I wouldn't be surprised if the new KH games showed up. I'm pretty sure FF13 will.
