I don't think he is ceo. He is president of Blizzard which reports to the Activision board. It's not a given that he will be fired but given he is in charge of how Bliz has reacted to the lawsuit and has been at the company mostly in a upper management positions for 15 years he may be seen as too compromised by association to continue as president if Bliz wants to show that they are doing things a new way. Keeping Brack on board is not much of a way to embrace new standards for conduct. Something tells me that Brack would be ok though. He probably has about $20m stashed away already on top of whatever golden parachute he is given.
