My Predictions:
FFXIV will finally get it's "Jeuno" in the recaptured city of Ala Mihgo, giving us a high level end game hub (tome vendors, market boards, inns etc.) in a multizone city as opposed to Mor Dhona/Idyllshire.
Samurai will get 1- 3 named Katanas and then go the way of Ninja with elaborately designed blades.
I also don't believe battle system/skill changes are going to be major and the battle system will more of less function as it is now. I don't see them going NGE when what's in place has more or less worked for them.
