I'm not 100% sure, but I'm like 95%. Someone said in the "Info Galore" thread that it was coming out for Wii, but I've looked at wikipedia, ign, and every Kingdom Harts site I know and it doesn't say anything about it... So, unless this guy is like a KH game creator, I'm pretty sure it's not coming to US anytime soon.
(Of course, they might say something at TGS!!!!)
