I think we're going to get a lot of changes moving forward, just because we're not getting it today doesn't mean we wont' get it later down the line and that it isn't being worked on.
The graphical update alone is huge, I don't believe that they'll just stop at that the impression I am getting is that 7.0 is essentially going to be a fresh start of sorts.
So I am expecting more overarching updates.

It's not like they're unaware of issues like the glam system, they're fully aware of it and have mentioned it multiple times before.
So it's clearly something on their minds which I assume they'd want to get around to when given a chance in a reasonable manner.
It makes sense to make the big changes with 7.0 since EW was the conclusion of what started in 1.0, EW needed to be more cohesive with the rest of the game.
With 7.0 tho they'll have a lot more freedom in this regard to make the game look and feel different.
