What happened to the Xbox fans cheering that COD was going exclusive as soon as the deal was announced? They all changed their tune when Phil signaled they need to pretend it won't so they can get this deal through, just like the Zenimax one. Kinda like how they were spouting BS about how Series X was going to blow away PS5 in every DF comparison, by 30% or more, only to change their tune when it didn't happen. It became, "Why do you guys care about these comparisons so much?"
As for your question, we learned about the backroom deal MS was trying to push on Sony, where they take COD away after this gen, while publicly acting like they would never take it away. Of course, the regulators didn't like that, so they tried to make it 10 years. In other words, if MS gets COD, it WILL be taken away from its largest audience, PS gamers. Fortunately, it seems like the CMA isn't quite down for that.
