Executive Phil Harrison is leaving Microsoft according to Gamesindustry.biz.
Phil Harrison joined Microsoft back in 2012 from Sony and then hired as head of the Xbox business by Don Mattrick.
When asked by Eurogamer at GDC, Xbox boss Phil Spencer only had this to say “I don’t, no. I’m sorry, I don’t think I can say anything about that,” In general it seems that Microsoft are refusing to comment at the moment, possibly waiting for a full Press Release.
