I tweeted this last night but...

Regarding the stuff posted on Famitsu for 2.2, that one only shows images and says mobs that looks like -----
Game Watch article has same images but went on further.

Amdapor Ruins boss is Diabolos
Brayflox HM boss is that Goblin face tank - JP name is Goblitank VI - You save Brayflox and them once again, this time fighting a group of goblins called "Blue hands" (JP name) saying Brayflox stole the recipe for some cheese.
Halatali HM is a new type of dungeon where you fight a series of bosses in colloseum style battle. Since the first Halatali, since the dungeon was cleared out of mobs the Gladiators guild have it changed into a colloseum for thier training but allowing adventurers to battle as well.
Marilith (Lamia - looking mob), Treant hybrid, Ochu hybrids are all BC.

For rest of info says to wait for the next live and hopefully we get something new.

Information above is from the article and may be changed before 2.2 launch so the story/names might be different, if they plan to change/for localization purpose.
