On July 29, 2024, Xbox will stop supporting the ability to purchase new games, DLC, and other entertainment content from the Xbox 360 Store on the console and the Xbox 360 Marketplace. This change will not affect your ability to play Xbox 360 games or DLC you have already purchased.
I can’t imagine the PS3 will last much longer than this. Truly the end of an era. :(
It’s quite a common misconception. The Wii Shop channel still works for downloading previously purchases titles for example.
