You only have to look as far as FFXI to guess where the future of FFXIV lies. More minor map updates that utilize existing map building assets featuring enemies that are also reused assets, or assets with different textures/skins over existing asset skeletons. Modular alterations of existing armor sets for drops. Besides, why dump tons of cash into developing additional content when people drop $$$ on mogstation just to /songbird in LimLom with the new moneyfashion.
