Before I begin no, this is not a rumor but a fact. Tetsuya Nomura the director of Final Fantasy Versus XIII has stated that they are gearing up to release more information on the Versus. Tetsuya also mentioned that Final Fantasy Versus XIII is a touchy subject. This could mean many things and the right thing to do is to see what Tetsuya and the rest of the team have to show the gaming community if anything. Check the link below for more on the subject.
As always thank you for reading.
