The only official confirmation we have ever had is that Yoshi-P would like it to be in game. It has never been confirmed to be coming at amytime in this games life. Theread was an event last year in summer which was to celebrate the second year of FFXIV since 2.0 launched. In it, we got hints about Bluemage and Redmage. Anything you hear about how they will play or what role it will fill is pure speculation from the community.
