Maybe I'm alone in thinking this, but a new round of Abyssea zones will kill this game much quicker than its current content development cycle.
There was a lot of people who liked it - and I did upon its release for a while. The ultimate problem is that Abyssea was a mediocre attempt at revitalizing the game. Square Enix can do much better, and if you're happy to settle for another 3 zones full of boring mobs all of which can be brewed ergo no real challenge - then good for you, but I'll be spending my money elsewhere if it comes to that... again.
