I think since most of us are from different rregion, we can't assume when the update is going to be out even though he said it's going to be February the 14. Some of us now have different 馃搮 date and time. Mine now is February 14 at 7 am.
From what I heard from Kail, he said that the 4.0 update will be RELEASE at roughly 12 midnight again. He may change the release date again but this is all I've heard from him. So 馃槑 calm yourself down guys and be patient.
