Yesterday we learned that the PC version of Destiny 2 will be on Battle.net, not Steam. What Bungie didn't tell us during the stream was that this version won't be ready by September 8.
The developers have confirmed that the PC version won't launch alongside the PlayStation 4 and Xbox One versions. They can't say when it'll be ready yet but promises that they're working hard to make the delay as short as possible.
Are you getting Destiny 2 on PC, PlayStation 4, or Xbox One?
