From what all I've seen...
It looks like there's going to be tempered in Ala Mhigo, meaning whatever is happening is possibly happening near the Ghimlyt Dark. We will be seeing what looks like an almost Bahamut creature (maybe one of the missing dragons?) we possibly have to fight, Ravana/Gilgamesh in Eden's Promise, along with a Cloud of Darkness fight, the possibility of an Ultimecia fight (take away your memories she says), the sister from Weapon trials being taken away, Zenos breaking what looks like his own sword he used, Zodiark, and much more. Things are about to get heavy, and we have no clue where we're going at this point. It's definitely leading up to the "series finale" for the Zodiark/Hydaelyn plot.
