I wonder if you will still be able to download patches and updates after the stores close? That is one thing I did not see any mention of.
I wish they would have a big fire sale, but I doubt that will happen
You'll probably will alongside trophy sync, but honestly you have to be pretty optimistic to believe Sony will actually keep other online functionality such as downloads working past 2021. If they didn't turn any profits on PSN now, imagine with the only place to actually give Sony money for PS3 stuff unavailable.
Hopefully piracy and muh preservashun nerds will snatch up the .pkgs from Sony's servers and fund an alternative one, but imagine the petabytes of misc packages in total on all region PSNs.
BTW if anyone cares I got my fat PS3, but it overheated like a motherfucker and basically killed itself on demanding games. I followed ChuChu Flamingo's tip (a real mvp) and I have the thermals working properly again on the console, it's seriously amazing that this is now running cooler than the Slim I killed. Definitely look up the "PS3 eraser fix/trick" if you have an overheating unit you'd like to use again, but don't want to potentially ruin it by attempting a delid.
