Dark and Light

March Update will have Alexander and Odin.

They didn't say how you get them. Just they they can only be summoned through the 2hr ability. Alexander puts a shield around the party (within the area around the summoner) and Odin does what he does, one-hit kills the mob, unless it's an NM then he just does damage.

I'm hoping that when this comes out I'll have them already since I've already beat both Alexander and Odin in battles. Since if there's new battles to get them that will be a real pain.

They also announced three new episode/expansions/updates/whatever so it looks like things are still going on vs. FF14
[edit]
Dangit, I picked the wrong post to look at first. You already mentioned this.
