It’s been nearly a year since the last DirectX SDK, back in August 2009, but Microsoft has finally published the specs and details for the next SDK, coming in June.  This version adds in Microsoft Visual Studio 2010 support, but drops Visual Studio 2005 support.  It also adds PIX object naming, the XNAMath C++ SIMD library, and a few new D3D functions.

You can read the full details on the MSDN blog.
