Don't set yourself up for dissapointment. WKC2 was never on TGS list, they had a little note that said there would be like 2 or 3 unannounced PS3 games. Famitsu says that there will be a trailer at TGS. So yes, WKC2 is one of them.
Of course. And I'm still betting on HSG6 with possible wand support.
