Recent analysis has stated that departure of Mattrick has nothing to do with Xbox One.
“Don’s been an industry pioneer and a key catalyst to Microsoft’s success in video games. He’s leaving behind a well-crafted and very skilled team of executives that are perfectly capable of carrying the torch”, as said by EEDAR’s Vice president of Insights wrote in response to our request for comment.
He also added that “Microsoft is in capable hands moving forward and I don’t think anyone anticipates Don’s departure to impact the Xbox One’s launch”. With this he also added that XBOX ONE DRM has nothing in relation with Mattrick’s departure.
