It might be sooner than that. The last 2 releases of new servers launched in March 16 of their respective years (Coirnav, Phinigel, Mangler). Three servers also launched in May (Ragefire, Lockjaw and Agnarr). I read something by a developer that implied that the team works on a calendar system when determining what should be worked on. For example, AA "balancing" or "work" is done in October/November. Note: I forgot about Miragul, but I am too lazy to change what I typed!
