Pretty much... take after their parent company.
I've seen a screenshot someone took of the Heavensward download on their JP Account. So it IS available... Hopefully when the PSN store resets next week, we'll see something similar for NA (NTSC) and EU (PAL) PSN stores... which as Australia is under PAL, we might see something for us Australian members. Just... need to know a idea of A: How much it'll be and B: Is the digital CE a limited time deal or not... If B is a yes, then I'm S.O.L. as I won't have the funds til 2 days after the reset >.<
