Sony needs something to replace Bethesda's single player RPGs.

I don't think Sony needs games to replace Bethesda's titles, they will likely do their own thing and release their own games rather than try and copy the competition, which would be a good thing for the market in my opinion, more differentiators for people to choose Xbox, Switch or Playstation, rather than clones of each other with a couple of exclusives,.
