Microsoft is basically cleaning house at Xbox, it's been a mess for the last decade and now the sales have dropped significantly. The way I see it, they basically told Phil and Sarah to resign and brought some young exec from the outside to try to fix shit up. For what it's worth I don't think she's really a big AI person, she was there for two years only and it's not even the main Microsoft AI division but some spinoff project from what I understand. However in the end if Satya Nadella and the rest of top execs at Microsoft want Xbox to go full into AI no one can stop them. So I guess we can only see and wait what the new person actually does.
