I just got an email from Sony stating that they are going to indeed close the store.
We are closing PlayStation™Store on PlayStation®3 on July 2nd, 2021 and on PlayStation®Vita devices on August 27th 2021. Additionally, the remaining purchase functionality for PSP™ (PlayStation®Portable) will also retire on July 2nd, 2021.
They further go on to say
After thoughtful consideration, we decided to make these changes in an effort to focus our resources for PlayStation Store on PlayStation®4 and PlayStation®5, which will enable us to enhance the customer experience even further.
I don’t see how this says it going to make the PS4, or PS5 better, in fact as I read this, it puts me further into the position of never wanting to buy digital games. As I can not be sure on the permanency of a digital “purchases” how long will I still be able to download what I bought (if I had bought something digitally).
This does prove the point I have said more then once here, digital is a bad idea, go physical. If the idea was to get people to buy digital in the future this is not the way to do it.
