Lets cut the noise. The bottom line is that CDPR is a significant upgrade over Guerrilla which is the studio Yurinka failed to mention but obviously alludes to - the WRPG studio line.
While Guerrila are extremely competent tech wise, with Decima being a world class engine they're extremely mediocre at world creation and story telling - that is, creating great memorable games. Even after supposedly stacking the deck with ex-CDPR story tellers Horizon Zero Dawn and sequel are still safe AAA mids. It's flashy, extremely polished, a tech marvel but the world and story, after a sequel, leaves a lot to be desired and they keep bumping on the same rock. This is emblematic of the same troubles they had with Killzone - a mid franchise. PlayStation fans obviously prop them up, specially when the quality is there to back it up (we all appreciate that hard work so rare in this industry) but the deficiencies of that studio to ship a stellar all around package and join the likes of Santa Monica or Naughty Dog continue unabated. They just can't make the jump to Bungie/ND/Santa Monica class - its been a long time now.
The question of acquiring CDPR revolves more around the ego of Herman Hulst more so than the merit of the acquisition itself or price. The Witcher and Cyberpunk IP, plus GoG as a working blueprint for a future PlayStation store front on PC has synergy written all over it. That is not to say there shouldn't be a careful look at CDPR, its leadership, management and leads - plus a gazillion other details but to dismiss them outright due to personal shuffling that occurs at every studio in this industry is disingenuous and misleading. Just look at ND turnover. Moreover, CDPR is CHEAP to maintain due to eastern european wage differentials. Cyberpunk was and is a great title which rightfully got shat on and destroyed by the shit CDPR management tried to pull - let that be a lesson, but we shouldn't blind ourselves to everything else.
So when I say it's about the ego of Herman, it's quite simple. If you acquire CDPR this studio will obviously suck the attention and resources in the WRPG line as Sony's next All-Star, to enable them to ship world class titles. I can bet you a million it will ruffle feathers with certain individuals and studios, specially Guerrilla which will see its niche inside the organization squeezed. Guerrilla is Herman's baby - on a personal level we probably can't comprehend what that studio means to him - it's literally his career. That love however should doesn't detract from the fact that they have a lot of mediocre leads who have been at Guerrilla for way to long with long careers in an industry where only the best truly shine and get the recognition and success.
CDPR is an upgrade over Guerrilla Games on a balanced scale of pros and cons, that is the bottomline. That is not to say if I were in a similar position as Herman I would outright disband Guerilla or fail to maintain their space - to the contrary. Guerrila has earned their stripes, if anything for their dependability and puntuality in shipping titles, something that you rarely see talked about when discussing Sony's in-house dev teams, but rest assured and look it up, when Sony needs a title shipped during critical crunch console launch windows, Guerilla has been there shipping the product. With that said this is business, so if you have a chance to get a Bungie, you do so, and if you have a chance to get a CDPR, you better do so as well. The man that has a lot of say in this regard, if not the most to say today is Herman Hulst.
Sony does not need another Kadokawa situation like with FromSoftware, if it can help it, imo.
