This is from awhile ago, so hopefully we’ll be able to see some of them:
A report from investor that held a meeting with MS last year:
"Microsoft believes that its new studios will help it to achieve a primary goal, the delivery of one AAA game per quarter in order to drive Xbox Game Pass. With that said, it does not want to rush its new studios into delivering games before they are fully baked, and believes that any acquisition takes time to get its legs. Its ideal acquisition targets have proven content and strong development teams."
