Destiny 2 has been confirmed by Xbox and Bungie for a PS5 and Xbox Series X release.
Bugine posted a tweet stating that the game will be available on next-gen platforms and a teaser GIF along with the tweet. More details are to be released later- which will probably have the rleease date.
There are rumors that Destiny 2 will utilize the Series X’s Smart Delivery, which allows you to play it on both consoles.
But that’s just wishful thinking at this point. I mean, would it make sense to buy it twice?
