At least some people are skeptical but willing to try XIV.
It's still in a closed BETA and has 1 million+ players. I've played every NA Final Fanatasy and RPG from SE since Mystic Quest and I can tell you if you're a FF fan missing XIV is completely your loss.
XI had great lore, and original ideas, but for once I'm seeing SE utilize all the amazing FF lore, and things that worked from previous games into one "True FF MMO" They've borrowed from
FF1: Warriors of Light
FF3: Crystal Tower
FF4: Dragoon AF, and some story
FF5: Jobs system
FF6: Magitek Riders, Empire
FF7: Materia, Aetheryte, Golden Saucer, Limit Breaks
FF11: Races, Monsters, 3 base cities, numerious other things,
FF12: Judge like Emperial Legetus's & Hunting Logs
FF13: numerious monsters, ideas
AND FFXIV:
Quests
in depth Crafting & Gathering
Primals and new beast tribes
Housing
unique story
new lore
new battlesystem
Many more new things..
This shows a good selection
