Yes, the Final Fantasy XIV Beta now has an official launch date. March 11, 2010. This is only the PC Beta, so those who bought Final Fantasy XIII in hopes of getting into the PS3 Beta will have to wait a little longer. This news is straight from Vanafest 2010, so feel free to go check out their website to confirm it for yourself.
Kuro Matsuri Video Games is, of course, in the pool of applicants to get into the FFXIV Beta. If we get in, we will be sure to bring you lots of news and videos about it.
