Aaron Greenberg:

"I'm excited by what's ahead. I will share that after spending dedicated time this week with our new Gaming CEO, @asha_shar I’m incredibly optimistic about the opportunity ahead under her leadership. Asha is exceptionally bright, eager to listen and learn from others, no ego, but wants to get Xbox and gaming in a direction I’m personally incredibly inspired by.

"A brave bias for action that starts first with great games, the return to Xbox starting with the console and a vision for the future. Paired with Matt Booty in his expanded role leading all of our creative games and entertainment teams we are well positioned to do the work we need to do. As a long time team member and as someone who cares deeply about Xbox, our games, players and the future I’m encouraged and eager to help us on the path ahead."

Greenberg's quote makes me think Xbox leadership has known about this for at least a little while. Phil retiring isn't a surprise given how long he has been at Microsoft. Still strange we've heard nothing from Sarah Bond. 

Phil Spencer and Matt Booty have updated their LinkedIn profiles, but as of right now Sarah Bond's hasn't.
