The problem is that to get in line with the story-based experience at low levels in other major MMORPGs nowadays, SE has a LOT to add before the PS3 rerelease.
As I said other games have evolved a lot from the "go gather 40 bear pelts". Even games that are considered average like Warhammer Online or Age of Conan offer very compelling story-based experiences at low level, with a lot more density than FFXIV does.

Increasing density during the initial levels (which is absolutely crucial to actually create a customerbase) doesn't mean neglecting the high levels. In fact the idea is exactly to increase the density of lower level content AND to add more at higher levels.
