I was about to talk about graphics =/= aesthetics but someone beat me to it...
Basically for those who don't know the difference:
Graphics are the capability to show something, aestetics are what they decide to show.
FFXIV has some of the best graphics of MMOs out there and is making them even better for 2.0.
Aesthetics aren't so great though (in most areas) since it's all just brown-greenish copy&paste landscape.
That's supposed to change with 2.0 as well.

Found a video explaining it a bit
