I don't expect PS5 to have it based on what we've seen so far
but if it doesn't, I'm out on Sony hardware I think. I realize I'm an edge case, but it's that important to me.
I've got a lot of PS3 Digital titles more or less held hostage on old hardware, games that I bought with the assumption that PS4 would have BC
I'm sick of endlessly rebuying the same games, I'll just stick to PC where I can my digital purchases seem to last longer. Especially if Sony 1st party stuff now comes there. I can be patient
