^ Cloud of Darkness is coming, there's no question. Won't be for a while as it's the final boss of CT (much like (I assume) Bahamut will be for Coil or something), but I am very excited for it!

One I want to see that won't already be coming to FFXIV based on spoilerish events (like a certain clash on a certain big bridge) is The Emperor's Battle Scene II. It'd be doubly amazing if, after Crystal Tower ends, Square-Enix would release a dungeon based on Pandaemonium/Arubboth, just for this.
