This State of Play from 10 months ago is the most we've actually heard on the game. There's a rumor going around that some first party Sony titles have been delayed out of 2023 and some were speculating that SB is a part of that but I'm not so sure. I think SB is still a ShiftUp property so it's possible that they still have plans to release in 2023. My guess would be holiday season.
As for if it's coming to PC or not, well that's tricky. The trailer says that it's a PlayStation Console Exclusive, this is terminology used in the past to reference the fact that a title is only coming to one console and not the other, this typically doesn't make reference to PC basically it's just a big middle finger to Xbox owners. I'm sure we can expect it on PC at some point though in what form and how soon I'm not sure. I'd love to be able to play this on Steam with a bunch of mods on release day, but knowing Sony it'll probably get put on the Epic launcher 6 months after release and then Steam 2 years after that. I hope that's not true but Sony has a track record of doing that.
