Bump.
I'd like to know this, as well.
I play on both PC and PS4, and I'm wondering if I'd really have to buy all skins, season passes, and so on twice over. Feels like it would be more convenient if I could use my PC account on the PS4, or vice versa for convenience. It would only be fair, as I'd otherwise have to spend an excess of $120 dollars on the game.
