Yeah. But that would also mean that Game Pass grew. Which will add additional revenue (and profit) into Game Pass bucket

Also, ABK revenue is not leaning towards game purchases that much. For example in six months of 2023 they earned:
1,2 billion in product sales
3,37 billion in in-game monetisation/sub/other revenue
And that was period that Diablo IV came out. In six months of 2022 they earned
690 million in product sales
2,72 billion in in-game monetisation/sub/other revenue
And since in-game monetisation is not covered with Game Pass and they will still have full price revenue from PlayStation consoles and even sales on PC and Xbox (can we stop pretending that you will sell nothing if you put your games into Game Pass? As we saw with Starfield for example?) I think that Microsoft will be more than fine
