Sony has their own platform and eco-system so it makes sense for them to be negative and they'll obviously lose money from the 30% cut they get on game sales and micro-transactions so they obviously can't be happy. I personally see Microsoft making every game exclusive once contracts are done. I don't see them pulling any previously released games including liver service games like Warzone 2. It will be the same as Bethesda, they keep everything that's already been released as is, keep releasing content for the live service games (in the case of Bethesda, like TESO and F76) and fulfill contractual obligations. But all new game releases will be 100% exclusive to Xbox/PC/Cloud as they should be and I do believe that the first exclusive COD game for Xbox will lead to Microsoft eliminating Gold and the online co-op/multi-player paywall. This is what could change the landscape of gaming because if one platform offers free online play while the other doesn't, why would you pay for PS Plus if you're an online gamer and especially if you mainly play COD?
The way this generation will play out over the next several years is going to be very interesting and im way more excited this generation than I was last generation because there's just so much more going on with Nintendo being once again dominant and Microsoft finally investing into Xbox after over a decade of barely putting any money into the platform and eco-system.
