Glu Mobile's long search for a new president and CEO isn't over but the incumbent Greg Ballard has decided he's had enough of hanging around.

This is unsurprising as he announced his departure in July 2009 and has only been keeping the seat warm while the process of finding his successor has been ongoing.

That mystery man (or woman) remains elusive however, so now the current co-chairman of Glu's board of directors, William J. Miller, has had to assume the position of interim president and CEO, effective from 1st December.

Glu said it expects to finally name a permanent successor to Ballard in early 2010, although hasn't confirmed whether it yet has a specific candidate in mind.
