The lights are on
Final Fantasy XIII-2 won't be out until December in Japan and January in North America, but a new website domain registration suggests that publisher Square Enix may already be thinking about the next sequel in line.
Fusible uncovered that Corporation Service Company, a registrar that Square has used for previous sites in the past, registered www.finalfantasyxiii-3.com earlier this week. Square has previously made a direct sequel to Final Fantasy X, but if FF XIII-3 ends up being real, it would be the first time for the publisher to make a second direct sequel to one of its mainline Final Fantasy games.
Then again, a domain registration is still a long way off from a game announcement. If Final Fantasy XIII-3 is really in the planning stages, I wouldn't expect to hear anything about it until XIII-2 is out the door.
