Just the PC, although I believe XIV is based on the idea that they will be dropping PS3 support at some point in the future, and in a long time, PS4 support as well, which is the healthy and proper way to handle MMO support of a console. The MMO either grows or it dies.
Letting a profitable MMO die is like letting your money tree break because you wouldn't water it. The water might be expensive, but growing a new money tree is notoriously hard and not always successful. Yet they certainly used the barely wilting leaves from one money tree to fund full time world class arborists to save a sapling that had snapped in half and previously caught fire, and when one of the arborists asked if they wanted to rig up a node for the barely wilting tree on their new irrigation system for free, they ripped a branch from that tree and started hitting him with the resulting stick.
