There is no release date, and there hasn't been...ever. Search the forums, please. The update will release when it is ready. That could be today, that could be mid-June, that could be July...just be patient.
It will come out when they are finished with the update.
if i assume that ibyro is answering the question(when do you *think* it will come out?) and not some made up question that may not have been asked(Q:how finished will it be when they release it?[A:when its half finished or finished]) then ibyro thinks the "release date" will come out when they are finished making the update. kinda funny when i thought about it, unless i have it wrong.
