The difference is if Sony buys Take 2, they will still remain multiplatform similar to Bungie. They have to, they wouldn't be able to afford for Take 2 to be exclusive.
If any company can make those big games exclusive, it is Sony.
Think about it: these big games do not usually release on Nintendo. And Xbox represents the smaller userbase. If Sony makes, say, GTA 6 a PS5 console exclusive, they lose out on hardly 25% of the sales. But increase their revenue from 30% to 100% -- which more than makes up for the lost revenue.
Rockstar games do not launch on PC day one anyway: both GTA and RDR 2 were timed console exclusives. RDR 1 did not even release on PC.
So Sony can release the games first on PS5 and later release them on PC 6-12 months later, and literally nothing would change -- except the lost ~20-25% revenue from Xbox sales (which, again, represent the least amount of sales).
