Hopefully it's actually optimized unlike the PS4 version. There's even a hack someone did in dev mode that lowered the resolution to 720p just to maintain 60fps. It's just tons of frame drops out of the box.

I wonder if it's like a taster for games you've missed on the PS system to tempt pc gamers to buy into the ecosystem when the PS 5 releases.
Looking at it from a business viewpoint they have already had their main chunk of sales on these titles that are meant to be coming to PC, There won't be a sudden upsurge in sales on these titles on PS4 so it makes sense to widen their revenue stream by releasing on a separate platform.
That's a self balancing phenomenon though.
Less people making hardware doesn't affect the demand significantly.
So each manufacturer gets a bigger slice of the pie.
Which attracts more manufacturers, which increases competition. So less pie.
Manufacturers drop out etc.
