I'm hoping we get a ray tracing update like WoW. Yoshida made a comment on the FFXVI website saying "Our next big information reveal is scheduled for 2021, so in the meantime, I expect everyone to have fun speculating, as we have a lot in store—not only for the newest entry in the series, FINAL FANTASY XVI, but for FINAL FANTASY XIV, too. Needless to say, I’ll be working hard on both!"

Now this could be an announcement for 6.0 or even a crossover event, but I feel SE needs to add a like graphics bump for FFXIV.
