At VanaFest 2012 in Japan, Square Enix revealed the fifth expansion to Final Fantasy XI with the upcoming release Seekers of Adoulin. This update will be released in 2013 on Xbox 360 and PC worldwide, but only Japan will receive the PlayStation 2 version.
Seekers will take players west to venture into new lands and encounter all new beastmen. Early talk is that exploration and discovering new areas will be a large focus in this expansion. There are also two new jobs to unlock in the Adoulin expansion: Geomancer and Rune Fencer. Geomancers will use Vana'diel's elemental forces to both aid allies and to take down foes. The Rune Fencer job harnesses arcane ruins for both offensive and defensive effects in combat.
More details will be revealed between now and the expansion's 2013 release, but we have some new media in the meantime. Also, check out the official Seekers of Adoulin website.
And on a side note, founding Squaresoft member and original producer of Final Fantasy XI Hiromichi Tanaka has left Square Enix. The official reason for this departure has been listed as health reasons. Akihiko Matsui will be replacing Tanaka on Final Fantasy XI and will be splitting his time between this and Final Fantasy XIV.
