Gamasutra had an interview with Crytek CEO Cevat Yerli, you can read it over here. When asked about 3D gaming, Yerli replied that he's quite sure that this will become standard over the years, and interestingly, he also revealed the Crytek is also involved in the development of simulation and training software for the military as well as oil and gas companies.
What kind of non-game stuff do you do?
CY: There is a whole industry in serious games, and we have a lot of contracts going on from gas and oil companies, General Electric, all the way to SOCOM. We have a lot of military companies working with our technology, in fact.
So you provide simulation and training software?
CY: Technologies, simulations, contract work, whatever they need and whatever they want. We have a studio for serious game development. That studio is a subsidiary of Crytek, but it's not called Crytek. It's studio number seven -- so secret I didn't even mention it! [laughs]
