Square Enix is going to enter the deep MMO waters once again as the Japanese publisher officially announced plans for Final Fantasy XIV (or 14 if you don't like Roman numbers) Online. The game's teaser site has already launched with a teaser trailer (naturally).

The game is due out on the PC and the PS3 in 2010 and aside from the teaser trailer andt the words "Adventure begins anew in the vast realm of Eorzea" no other info on the game has been revealed. Our sister site Massively has some pictures from the Sony press conference where the news was first announced.
