Neither Microsoft's Windows 8 operating system, nor the rumored Windows "Blue" 8.1, could ship with a newer DirectX version. Taylor was responding to a question from Heise about next-generation GPUs and technologies they could be built around, to which he replied that normally, new DirectX versions stimulate introduction of new GPU architectures, but there won't be a DirectX 12, and so the company's next-generation GPUs will integrate other technologies.Taylor also revealed that Battlefield 4 could be part of an upcoming Never Settle gaming bundle.
