Recent job postings on Square Enix’s European website show that a beta for Final Fantasy XIV may start as early as September.
Several job posts for Game Masters and Game Testers have appeared on the job page for Square Enix Europe. Each of the job openings requires the applicant be familiar with Final Fantasy XI, suggesting that the current support team for FFXI will be moved over into FFXIV.
Testing positions are said to have started towards the beginning of the month, which means that a closed or internal beta is currently being conducted. Game Master positions are said to be starting in mid-September making us guess that a beta could start shortly after.
