Ok, I've said this in other places, and I'll say it again. This was in a conference about titles in Japan. Most likely, Skyward Sword will come out in all 3 regions around the same time, as that's usually the case with Zelda games. Now, in Japan, OOT is expected around April-May, and they said Skyward Sword is coming out AFTER OOT, assuming this means Japanese release wise. So I say Skyward Sword is coming out May. Now the reason OOT won't be coming out in all 3 regions at the same time is because of hardware related reasons with the 3DS.
