So far, the announced platforms for initial release are PC/Mac, PS4 and XBox One, as detailed at the end of the spoiler video. Other platforms may be considered later.
Agreed. The videos/images released thus far have been pre-alpha versions, before balancing has been done. There's no guarantee that anything shown will make it into the final product as shown, though the basis ideas most likely will. There's still a lot of work to be done.
So these are of alpha? Last I checked it was in beta. Cool to see the game is going well!
