Firstly I want to make a point to all those ( THERE'S GOING TO BE MOAR MODES) people, that there won't be any more modes, just Extreme begin the highest. Secondly, Hard and Extreme modes will all come in 1 patch. Levi in 2.2 will have both Hard and Extreme modes.

In other words you can look forward to "new" content that isn't rehashed from 1 patch to the next.Yoshida: In the future, primal battles will be released at the same time. For example, in patch 2.2, we will add both the hard and extreme mode Leviathan battles to the game. We will also be adding the extreme mode King Moggle Mogg XII in patch 2.2, so there will actually be three of these battles added at once in 2.2.
Now looking forward to 2.2 things we will see and possibly see:
1) Leviathan (Hard and Extreme)- Coming in 2.2
2) Extreme Mode of Moogle- Coming in 2.2
3) Gilgamesh might make an appearance as a boss fight in either 2.2 or 2.3. ( Crossing fingers for 2.2)
4) Free Companies maybe able to summon Primals in 2.2 ( if not in 2.2 then in 2.3)
5) Story will be 1.5 times longer in 2.2 than 2.1
6) Coil will get added turns (6-10?) in 2.2
7) Housing will be getting an update(s) in 2.2
8) PvP will be getting an update(s) in 2.2 (New game rules?)
9) In 2.2 All Beastman stories will be in the game (that are currently in the game now, Sahagin and Kobolds) - In the future they maybe adding additional Beastman ( Like Mamool Ja)
10) Chocobo Raising maybe in 2.2 ( note that he didn't say 2.2 or any patch this is just a "maybe".
11) He also said new Primal Fights ( not just 1) in 2.2We'll also be adding new play elements such as chocobo raising in the Chocobo stables which will be added in one of the upcoming updates to housing. We plan to add at least one element like this to housing with each patch.
12) Vanity will be coming in 2.2 ( they put so much emphasis on Vanity in Live letter XI XD)New Primal fights will be introduced. Yoshida stated that they will be “ones that new players haven’t even imagined.”
13) 2 Hard mode dungeons and 1 New Dungeon/ New Haircuts from the Barber ( Thanks Megamilk)
This is all I could gather up right now, but it seems 2.2 is going to be bigger than 2.1.
