Ah, welcome time traveller. Can you take me back to 2008 with you? It was so much nicer there.
Seriously, every multiplayer game I've played the last few years has cross-platform play, both them and Sony have been making PC ports for ages and the reason I own a Series X is that it's quietly the best set-top media player out there, price-to-performance, and a cheap, convenient platform to play games on a TV.
I mean, if this is a prelude to them no longer making hardware I'd be bummed out, but not for those reasons.
