At their conference in Japan, Square Enix has just confirmed that Final Fantasy XIII-2 will launch this year (2011) in Japan. The game will be directed by Motomu Toriyama.
Few details are known about the game, though it will mark the return of protagonist Lightning. VG247's snagged a picture of the game's logo above. Cheers for that guys.
We'll update with more information once it filters through.
