Microsoft is currently holding another WinHec conference in China where it is showcasing the latest Windows 7 build 6956. Several Chinese tech sites have posted screenshots of the latest build. The latest build does not contain that many changes to previous builds. Most notably are the new Windows 7 start screen. The other notable change is an increase in the Windows Experience Index which is now ranging from 1.0 to 7.9.
There is also another screenshot that is showing a DirectX 11 booth.
