PlayStation Universe is reporting that Final Fantasy XIII has been confirmed for release in 2008. The news is based on an interview with Tetsuya Nomura (Director of Final Fantasy Versus XIII), which appeared in the January 19 issue of Japan's Famitsu magazine (the cover of which we've photographed here to make Joystiq prettier).
Closer inspection of the interview reveals that Nomura simply made the following statement with regard to Versus XIII:
"We're planning to have the final in-game graphics prepared at some point during 2007, so please wait for that -- and then we can speak about Versus XIII in more detail."
In light of that, a 2007 release for Versus XIII does seem unlikely, we admit, although not impossible. Release timings for Final Fantasy XIII and Agito XIII are not mentioned, though, and in the latest issue of Famitsu (February 9) all three games are still listed as having "unconfirmed" release dates.
