Xbox One boss Don Mattrick 'resigns'
Microsoft head of entertainment and devices said to be joining Zynga as CEO
Don Mattrick, the most senior executive within Microsoft's Interactive Entertainment Business, has allegedly announced his intention to leave the company.

According to The Wall Street Journal, Mattrick is departing to take up the role of chief executive officer at beleaguered social games group Zynga.
Microsoft has declined to comment
Mattrick made himself the global face of the Xbox One project, being the first executive to introduce the system at Microsoft's Redmond campus in May, and the man who officially announced the dramatic Xbox One DRM policy reversal - a move which undermined many of the console's core features that MAttrick and his team spent years building.
Insider sources claim that Mattrick is in line for the role of CEO at the struggling social games firm Zynga, in a move that would represent a major shake-up for the business that recently announced further layoffs and studio closures.
His departure, which has not been officially confirmed at the time of going to press, comes several months ahead of the global launch of Microsoft's third major games console.
