According to Microsoft CEO Satya Nadella, MS will be considering purchasing even more studios for Xbox brand in the future

"You can't wake up one day and say, 'Let me build a game studio'"

Sounds like Bethesda isn't the last purchase coming https://www.cnet.com/news/how-microsofts-ceo-xbox-head-say-they-wont-screw-up-bethesda/

Microsoft got so sick of people saying they don't have any games they decided to go out and buy the entire industry

Realistically though for Microsoft's vision this makes sense

They want games hitting Game Pass every single month. 23 studios is a TON but even with that big of a fource they still aren't quite there yet

I wouldn't be shocked at all to see that number hit 30 1st party studios
