You know what else is possible in 2.1?
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!
