The new PlayStation Store set to launch on web and mobile later this October will remove games and add-ons from the PlayStation 3, the PlayStation Portable and the PlayStation Vita from the storefront. Apps, themes, avatars, and the wishlist feature will also be removed.
These items will no longer be available to buy on the PS Store on desktop or mobile, but players will still be able to buy them on PS3, PSP or PS Vita through the store on those platforms. The PS4's apps, themes and avatars can still be downloaded through the PS Store on that console.
Any content that's already been purchased will still be accessible as before.
With this change, PSP owners will only be able to buy PSP content through a PS3 or Vita, as that device's store shut down in 2016.
The new PlayStation Store will be native to the PlayStation 5 rather than a standalone app. Although that is certainly an improvement over the slow and cumbersome app experience from previous consoles, it appears to have come at a cost.
