After Bungie announced Destiny: Rise of Iron earlier this week, various digital retailers let slip that the expansion would come to Xbox One and PlayStation 4 systems on September 20 by posting store pages for the game. There were no listings for Xbox 360 or PS3 versions. In its latest blog update, Bungie confirmed that older hardware will not receive the expansion, though there will be content coming their way.
"From here on out, we’ll be referring to the PlayStation 3 and the Xbox 360 as legacy consoles. If you’re using a legacy console to play Destiny, you’ll need to upgrade your hardware to experience the next adventure."
Never fear: if you're playing on a "legacy console," Bungie's still got your back. "Up to this point, player progression between current and legacy consoles in the same family has been shared by each account. This summer, that experience will fork into two parallel experiences that will no longer share progression."
The idea seems to be that if you have an Xbox One and a 360—or a PS4 and PS3—your game progress will split on your PSN account, with legacy progress being stored separately. This is only speculation, however.
Bungie concluded the blog by promising a full explanation of how this separate path will work later this summer.
