I would not put too much stock into whatever Epic/Tim Sweeney has to say, frankly. The unreal engine may be visually impressive, but it is incredibly clunky and inefficient compared with just about any other engine out there at the moment and always has been. Tim is the guy who is claiming that unless your hardware fully accelerates FP32 his next title won't even run properly on your machine.
Yeah... it's not a good idea to trust what a big name programmer who created one of the most successful, excellent game engines ever says. It's better to trust some random fanboy named gstanford, who probably doesn't know WTF hes talking about...
