Square-Enix tweeted that the final test for phase 3 of the beta will begin on July 10th and conclude on the 15th. This test will take place for both North America and Europe. Following phase 3, FFXIV will move into phase 4, also known as "open beta."
Final Fantasy XIV: A Realm Reborn's launch is scheduled for August 27th. We covered the heck out of this title at E3, including its PlayStation 4 plans, a hands-on with its demo, a look at its PlayStation 3 user interface, a video overview of the FATEs system, and our thoughts on its convention appearance.
