But there is no case by case basis. Unless im very wrong I don't see another Bethesda game on PS again. Do you think there will be? Also ghostwire and deathloop were pre existing contracts signed before the acquisition, so they don't count towards anything. If there are ever sequels to both those games they would be xbox and pc only. Case by case was just another phrase with no substance. Microsoft are the King's of doing that.
MS continues to support all games that are on PlayStation with new content like ESO and Fallout 76. They also released that Quake remaster title on PlayStation after they acquired Bethesda and they did not have to.
Honoring the Ghostwire Toyko and Deathloop deals does mean something because the argument made here is that MS cannot be trusted and doesn't honor contracts made with PlayStation and other platforms. If they upheld the deals with those two games why would they now be lying about CoD?
Most of this is still moot because MS unless contractually obligated does not have to put ANY of their IP on non-Xbox platforms but they do so far more often other platform holders. Xbox games will hit non-Xbox platforms on a case by case basis. Not every game is promised to every platform.
