I have a PS4 pro and have a lot of fun with it still, it's only the Xbox that became pointless heh. The pro has its serious issues like it's stupidly loud, the lods are just as bad and the pad is worse especially for fpss but at least it has exclusives to differentiate it from PCs.
I mean, Halo Infinite is coming to PC (afaik), what's the point. Just spend the money on a new gpu and plug it to the TV. The only group that would seem to be the target is people scared of installing drivers, surely not mighty PC enthusiasts, you're giving up control over vsync, film grain, res, detail settings, frame rate, AA, AF, mods, not sure for what exactly.
