Not too long ago, Sony announced that the Playstation Store will no longer be accessible on the PSP after March 31, 2016 for North America. Before that date, you can still purchase & download stuff on your PSP. After that date, you can purchase & download PSP stuff from the web store & possibly the PS3.
In all honestly, I am surprised that the store lasted this long. I know that there have been a very small handful of PSP games popping up in the last 6 months or so. But, I didn’t think the store was still going. Thought it went offline a few months after Sony discontinued the PSP here. I don’t think it will be a big loss really since most people have a computer or some form to purchase or download PSP games on to. Also, I assume some people have moved to a PS Vita & that system can play PSP games without problems.
I guess at the end of March is where the PSP system will finally rest. Although I did make a post about the death of PSP 2 years ago, but I guess this time it will be truly the end.
