They don't even seem to be that expensive. I'm surprised that MS didn't already try to buy them if they are really only worth a few billions like I just read. You would get huge IPs and big studios for much less as some public gaming companies would cost.
A Bloomberg article from 2016 says they are worth 2.5 billion. Not sure about now but with their problems the last years I guess it won't be a crazy number nowadays.
And spending some billion to purchase a company isn't really something crazy for big public companies.
Doesn't sound too expensive for Sony who need to succeed in the gaming industry since it's so important for them. Sure, the PS5 will be a success even without such a purchase but Sony needs to plan for a future with much less revenue from consoles while still increasing their revenue/profit from gaming.
