I wonder how many people would champion this if the title read 'Sony' and not 'Microsoft'.
Don't mind me, just a man walking through...
Absolutely, there'd be some. There are some valid concerns about anti-trust WRT how much Microsoft has bought out developers, and the Kotick conundrum (which was already pretty cut and dry in terms of a resolution) but if anybody actually thinks that COD or Overwatch are going exclusive at any point then they are wrong. Likewise, pretty certain both parties more or less confirmed that the main intent of this deal is metaverse related, with King being a secondary benefit. The actual game franchises? Basically bonuses.
If the metaverse angle is the filet mignon, and the mobile potential the baked potato, then the franchises themselves are basically the side salad. And I seriously doubt that either of the two biggest names in this scenario go Xbox exclusive. But really...it all hinges on Sony. Considering how much the split in terms of player base on COD on console was titled towards Playstation (after it was the other way around for much of the previous generation by way of the DLC exclusivity arrangement with Microsoft) does Sony really believe that burning that potential player base simply because Microsoft is a publisher on the boot up screen is a good thing? They'd be absolutely silly to.
Even the worst COD title (which you could make the argument Vanguard is) is still a guaranteed top 3 seller on a console marketplace. Hell, pretty certain MW19 was still in the top 10 for PSN digital sales for 2021, and that was before the Vanguard integration borked the game hard. That's a lot of money to leave on the table if you are Sony, since it's clear Microsoft stopped giving a **** about appearing on other platforms.
