Zynga announced recently that Dave Wehner will be the new CFO. He is the former managing director at Allen & Co. and will be replacing Mark Vranesh, who becomes Zynga s chief accounting officer.

Sources close to the matter indicate that this move does not signal an imminent IPO, but may lead to more acquisitions on the horizon. Zynga is estimated to be worth something in the realm of four to five billion dollars.
