Ain't nobody going to stop MS from making CoD exclusive if they want, something like that is never going to happen and doesn't even make sense. Any publisher can chose where to release their games and MS buying CoD doesn't get them anywhere close to any sort of monopoly.Even if Sony honestly believes otherwise, they'd never say it. That'd be extremely stupid of them.
What is their goal right now with the MS/ABK acquisition? (1) the acquisition doesn't go through, or (2) the acquisition does go through but COD and other big IPs remain multiplatform, and MS does not create a competitive advantage for them by offering COD on Gamepass day one.
How can Sony achieve that goal? By over-hyping the importance of COD and making it a bigger deal, i.e., COD is a category on its own, no franchise or IP rivals it, no other studio can make it, it moves consoles, etc.
Imagine if Sony just showed big dick energy and said, "COD is meh. Our studios are better. We can make a COD whenever we want to."
The FTC would be like, "oh, then there is no problem with MS buying and locking COD, we guess. Let's finalize and close the acquisition, and MS can do whatever they want: make COD exclusive, put it on GP day one, or whatever. It's not like that'll hurt their competition at all."
CoD, day one on Gamepass, Xbox exclusive, do it Phil, I dare you, but please publish the sales so we can all laugh.
