According to this AP report about positive trading on Take-Two's stock today, "the company's contract with Sam and Dan Houser, the heads of its Rockstar Games studio, expires in early 2008, and has yet to be renewed."
The news will certainly raise eyebrows considering the proximity to the launch of GTA IV, now confirmed for release on April 29. The Houser's are the notorious drivers of the Grand Theft Auto franchise, renowned by those in the know for keeping a very tight hold on Rockstar's reins and being fiercely protective of the brand and its properties. And their mother was in Get Carter. They told us so 10 years ago.
Maybe the big men are looking for a change? Sam and Dan were original Rockstar founders in 1998, along with Terry Donovan and Jamie King. Back then the Housers were touting the top-down GTA2 (we interviewed them at E3 that year) and everything was very bed-of-roses compared to the megalithic creation we see today in the 3D GTA. Is enough enough, chaps?
Don't expect official comment any time soon.
