Heavensward Not a System Time Buy? How?

[Bonah]

From everything I've read, it would seem that people who play on both ps4/ps3 and PC will need to buy the expansion twice to access the content on both systems. I can't seem to find any posts by a Dev anywhere on the matter. Let's completely disregard the fact that this is a horrible, moneygrubbing idea that seriously puts me off purchasing even a single copy of the expansion, even though I know I'll probably give into buying two.

How in the world is this going to work? I can kinda of understand restricted areas, you'll get auto teleported to a nonexpansion area if you login to a system where you only have the base FF14 and not the expansion. But there will be expansion specific items. Will these items stop functioning if you only have the base FF14? If that's the case, someone who has the expansion on one system and doesn't on the other would have to create completely separate gear sets for each system.

Overall, this is a horrible idea and the expansion should be account bound, similar to collector's edition and preorder bonuses, not system bound. If there are any posts confirming or denying whether or not multiple platform users will have to buy multiple expansion copies, please link me to them.
