Another month, another executive dropout for Zynga

Newsbrief: Zynga continued to hemorrhage executives this month, with two vice presidents of games and a vice president of the company's casino division all leaving following the appointment of Don Mattrick. The social game company has been losing executives left right and center for quite a while now -- just last month it lost the man leading its third-party efforts, and the head of its China offices. Now, according to sources at Bloomberg, Zynga's senior vice president of games John Osvald has resigned from the company, as has Nathan Etter, another vice president of games. And Jesse Janosov, vice president of Zynga's casino division, has also jumped ship. Gamasutra has contacted Zynga for confirmation.
