Tetsuya Nomura, in the latest Famitsu stated that development is indeed going smooth other then one thing and that is the map system. Due to this they are changing the map to be more like one found in an unnamed Final Fantasy title.

So because of the last minute changes, it is unlikely FFXIII Versus will be shown.

I’m guessing the game will be available in the year 6578 on the PS 930.
