In theory, what's stopping Microsoft from signing an exclusivity deal with Activision similar to what Sony does all the time? Say, for $69B, all future titles are Microsoft exclusive?
It'd be hard to block that deal as Sony has been signing exclusives for so long. And, like, you can't *make* Activision make Sony games. Hell, if I were Activision leadership wanting this deal to go through, I'd stop supporting Sony systems out of spite. "We offered you CoD for ten years. That wasn't good enough. Now, you get nothing. Good day, sir."
I still don't care, as the last Activision game I purchased was Skylanders... but Microsoft mentioned the Hexen franchise, something Activision hasn't done in years, so the chance to get another entry into that would be great.
