All the counter arguments suggest is the existence of a possibility in making it work. However, they are unlikely at best because anybody who seriously reflects on how SE has done things so far with FFXIV (back since late 1.0) will be able to tell that they're preparing a story here that is leading up to the release of Rogue and Ninja, which will be treated as a sort of "live" event in the story.

The way I predict it works is a basic side quest(line) leading to unlocking Rogue is introduced. This sidequest further elaborates on the already introduced Fraternity backstory and involves Thancred (probably a quest from him that leads you to the now public face of the Fraternity (Rogue Guild). From there on, once you hit level 30 Rogue, you are sent to Yugiri who then proceeds to be the Ninja questline NPC.
