id's John Carmack and ZeniMax CEO on The Acquisition on JoyStiq discusses the ZeniMax acquisition of id Software. They point out that along the way, the id Technical Director and former co-owner indicates one thing that's changing in the future is that they will be bringing all development back in-house: "As we look back at the things with the external teams working on it, we've had some hits and some misses with that. It hasn't had the same record that our internally developed titles have, and what all of the publishers expressed to us when we were shopping future titles around was: it was going to be so much more valuable for everyone if we did develop them internally, and that was why we had already started the process of staffing up and working on the Doom 4 project and the idea was that eventually, we were going to wind up with three teams."
