They are changing it a lot. Lots of things different from E3 build to Gamescom build.
I am also sad to see they changed the icons for Jobs, I really dont like the gold engraved style, i much prefer the current setup. This is what I mean:
But it is such a tiny thing that I'm just nitpicking.
I also find this to be very disgusting and out of place, but I know there will be likely a toggle for it so no worries:
These are the only 2 things i can think of that I dislike, everything else I think is absolutely fantastic, i love the design, the functionality, and placement (though you can move it). The additions are also welcomed such as X/Y on minimap and Gil/gear slots always visible.
