The other half of Mor Dhona and Coerthas map :P. 2.1 is essentially bringing the rest of the content back into the game.

- Crystal Tower
- Moogle






Griffon's Crossing is blocked off ( when in 1.0 it was accessible to another area). They also would want to prep the areas for the expansion that is to come probably in a year.

You could say 2.1 is the patch that actually starts ARR ( unofficially anyways).

Could possibly see things like:

1) Hamlets
2) Chocobo Escort
3) More GC missions

What we saw here: http://na.finalfantasyxiv.com/pr/blog/000494.html is only a Preview. So, I am just keeping the hope alive of more exciting things to come!
