There are 5 seperate mapping achievements for the Coilings of Bahamat and there are, I counted, 12 dungeons some of which are prolly max level.

I also saw some supposition the some of the dungeons are 8 man.

There was a relic armor quest in v1.0 which I think is continuing, and they'll add more content at the level cap in each pass.

So there will be lots do to if you can play the game. My worry is that they're not going to have the server infrastructure for everyone who wants to play to be able to play. Least not outside Japan. And that is sad.
