[Dev Question] Will we need to buy Heavensward twice if we play on both PC and PS4?

to those saying you do with XI i will say thats a 2006 game that still follows 2006 practices. so i am hoping this will be updated.

I wanna know where you get this year from....

FFXI was released in Japan on May 16, 2002, for Sony's PlayStation 2, and for Microsoft's Windows-based personal computers in November of that year.

so no it isn't a 2006 game with 2006 practices
