That I do not recall but I wont rule it out, if there is a new super weapon then thats something different entirely, but it sounds possible. I would have to wonder what they will be about. Relics are about Attack/Acc bonus, unique Aftermath, and additional effects. Mythics are about job specific super weapons to augment the job itself, while giving a boost to a job specific WS. Emps are built on a great WS, with an extra boost in the form of +10~20 of the attribute that is the mods on the WS. So I am kinda curious what would come next.
