Is this cross platform with PS4?

So far, I don't think it is since their game is on a single server and you can't find your friends on the search menu (on the pc version of course since they don't support find a friend on ps4 at all). It's probably because the contents are different in both games and so it's not available yet but I sure hope it would be soon enough.

No.

PC players can't play with players on the Xbox, and PC players can't play with players on the PS4, and i don't think that any Xbox players can play with players on the PS4.

Neither can players on the russian shard play with players on the international shard.

And it's highly doubtfull, that any kind of cross platform playing is going to happen "soon" either.

The game versions are different between the platforms.
The in game "economy" is different between the platforms.
Not to mention the massive amount of work, they would have to put in for new client and shard software...
