The guys at Kotaku take a convincing look at what exactly might be going on behind the UT3 roll out. Is Epic's engine not all it's cracked up to be?

"Though, isn't it telling that SK ditched the Unreal Engine 3 all together and created its own engine? Or how about games using the U3E have been delayed or scrapped? Games like Stranglehold, BioShock, Lost Odyssey, Mass Effect, Rainbow Six: Vegas, Turok, Frame City Killer, Fatal Inertia and Brothers in Arms: Hell's Highway. All delayed."
