I think MS is completely right on what they said there, with an exception: they "forgot" to mention that their commitment to keep CoD on PS was only limited to 3 years more in addition to the already signed ones.
But as MS mentions, making it exclusive wouldn't make sense financially for them and wouldn't hurt Sony at all, PS barely would notice it and would continue being the console market leader.
That makes no sense, in that case they would be in favor of it. Sony even if they have the pennies are not dropping more than a few billion on a pub. So EA and T2 are off the list. Sony dont seem like the kind to spend tens of billions on acquisition for PlayStation, they would be better off just selling PS to meta , apple or google than compete with MS consolidation efforts.
MS needs huge acquisitions to get closer to the market leader, Sony. So it's easier that MS would get greenlighted such huge acquisitions once regulators like CMA and others properly investigate the market numbers.
Sony is in a market leader position, so doesn't need to make big efforts on acquisitions. PS is the biggest platform for the biggest 3rd parties, so the biggest 3rd parties will continue supporting them without needing to be acquired as long as they continue being as super successful as they are and don't need to sell.
To make smaller acquisitions to expand and grow in certain key areas where they don't excel (PC and mobile, FPS, MP, GaaS) makes sense for Sony. But huge acquisitions of big publishers would only make sense for Sony if they think that key strategic 3rd parties, the ones who clearly dominate key genres or game types that Sony doesn't have more than covered with 1st and 2nd party efforts.
ABK is not one of them. ABK is the best selling 3rd party publisher in console, and CoD may be the best selling 3rd party game, but the genres covered by ABK have a lot of other super performing games of that type (GaaS, MP, shooter, FPS in case of CoD) performing great on PS. So ABK or Take 2 being acquired by MS wouldn't be a huge loss for Sony because there are many games of these types performing great on PS. If Sony loses CoD they will continue having a lot of GaaS, MP, shooters, FPS on their platform. If they lose Take 2 they'll continue having a lot of top open world and sports games on PS.
If something, the acquisition of Square Enix, Bandai Namco and Capcom would be more dangerous for them because these companies have a major share of the userbase of certain key genres. That could worry Sony a bit, or could some day make Sony try to acquire them to secure them from anyone who would want to make them exclusive for rival platforms.
