So there is this note which changed my initial reaction. But it means on xbox 360 you won’t be able to buy new after next year.
Can I still buy and play Xbox 360 backward-compatible titles?
There is no impact to purchasing or playing backward-compatible Xbox 360 titles. After July 29, 2024, you will still be able to purchase hundreds of great backward-compatible Xbox 360 and Original Xbox games and DLC on Xbox One, Xbox Series X|S, and Xbox.com. We believe in celebrating gaming’s rich history and have worked hard to preserve as many games as possible through our backward-compatibility program. You can find the full list of backward-compatible titles here.
In light of the sad Xbox 360 news, I really hope we get at least one more run of BC titles once ABK closes. Also, stuff like this just emphasizes how important emulation is in this industry. I want to upgrade my Series S in the future and turn it into an emulation machine.
My understanding was that any 360 title not in the BC program for One/Series will no longer be purchasable, but I could be wrong.
There is also a small number of BC titles that have already become un-purchasable in the past because they left the xbox 360 store (RUSE and one of the Prince of Persia games and Daytona USA are examples)
