Sony owns Rapture and Helldivers. I see that as them testing the waters. While I don't think they'll ever do a same-day PC release, I think something like PS Now on PC seems highly likely given that they've already said they want that service on more devices.
I thought sony didn't own rapture. https://twitter.com/ChineseRoom/status/699342221775147010?ref_src=twsrc^tfw
