Some people are just burned out on Abyssea is all. Chill out, take a seat and wait.
You have a lot of faith in them, given everything I've seen since Abyssea I don't have that personally. They refuse to say anything about any kind of expansions, the updates since Abyssea have been really really cheap (fixing little things instead of giving strong new content that's needed with increasing the level cap). What the heck is the point of increasing the cap up and up and doing nothing with it? We should be getting addon packs with each level cap increase and lots of content besides, not like we are paying cheap subs to not demand proper quality content.
