I see a lot of people talking about the Blue vs Red reference, you guys must not forget that Heavenward have 蒼天(blue sky) in it title and Stormblood have 紅蓮 (red lotus) on the title. So most of these references are from the transition from the blue themed Ishgard to the Red themed Ala Mhigo. Maybe we will get blue mage, but I sincerely believe most of these references are for the expansions, not teasing any job.
