Back in 2.0 release time when discussion about New Jobs such as Ninja, Red Mage, and "Gun" Job there was mention of a Gunblade Job but Yoshi-P state he is holding it off for once we begin moving into Garlemald or can access the Capital City of the Garlean Empire.

If Yoshi-P still hold on to this statement now since it has been 4 years since he last stated this expect Gunblade Job for either 5.0 or 6.0 depending on which will the the Garlemald Expansion.
