This is another one of those somewhat misleading news stories. Square Enix has stated that Final Fantasy XIV will be ending its run on November 11th, 2012. The game will then be replaced by Final Fantasy XIV: A Realm Reborn. So in reality its more like a large content update than a game closure.
Square Enix has also started the alpha test for the Realm Reborn version of the game and you can sign up for it on their website.
I never played Final Fantasy XIV but the common word on it was that it was not very good. Hopefully the Realm Reborn update will breath new life into the game for those who purchased it.
