When is Kingdom Hearts III coming out

Kingdom Hearts III has not even been started yet for all we know. The only information that we have about Kingdom Hearts III is that Tetsuya Nomura said he will start working on it once he is done with the Final Fantasy XIII (13) games.

As RoxasDive stated, Kingdom Hearts 3 has not started yet and is dependent on the final result of Final Fantasy: Versus XIII. Also, as a slight note, KH3 will also be the end of the Xehanort Saga.
