The good news is that SOE is looking into character transfers that will allow players to jump between PC and PlayStation 4 versions. The bad news is that, at least for now, cross-platform play isn't possible.
"Because of the update cadence, and the additional steps you have to go through to be able to release an update on the PlayStation network, we're not going to be able to keep our servers in sync, so you won't be able to just play with the same people," said Higby. "But we're also talking about having character portability, so a PC character could transfer to PlayStation 4 and then back. The character format's the same on both; it's just purely a matter of the server updates."
