Errrr they can't really ask someone for large experience on PS5 development (which doesn't exist) or even PS4 because for those they already would have the listing of ex-employees.
So they are just asking for general experienced people that could have been on 3rd party developers that worked on PS4 or even people that only worked for PC versions of games. The trick is that someone that have large experience on PC could learn the differences to PS5 or even write parts that are equivalent between it and PC.
Just a ludicrous rumor since Sony said they would put in PC games that would make sense. TLOU2 is an exclusive that push HW so they won't make it multiplat (well besides working on 2 PS consoles).
