"Bobby Kotick will continue to serve as CEO of Activision Blizzard, and he and his team will maintain their focus on driving efforts to further strengthen the company’s culture and accelerate business growth."

I'm expecting/hoping for Microsoft employees to protest his involvement. They have successfully steered Microsoft in the past.

If they fire him after taking over can't they give him less in severance for the many reasons why he is hated?

However, they could also be withholding that until next week so they can get more news out of this acquisition, saying that he (and hopefully a lot of management) is stepping down would make a lot of news on its own, doing it now would muddle it.
