The claims of XBOX exclusivity were greatly exaggerated.
It seems the PS4 version will follow along after the XBOX version in due course.
But it has also come out that the PC Elite community won't be able to pew-pew with their console cousins, mainly due to the constrained and limited nature of console software updates in Microsoft's and SONY's walled gardens.
David Braben, speaking in an interview with games website PC Games N said “I think the challenges for us, which sort of fights against it, is we’ve also said that we’ll continue to do updates across all platforms, and what we didn’t want was PC updates to be held up for whatever reason, like if there’s a delay on another platform."
It's pretty clear that if the PC community were told an update was on infinite hold while SONY or Microsoft signed off on the console version, the news would go down like a cup of cold sick.
