@Dr Herbie: The net new - from a platform perspective - is Metro, though. The idea is to give devs a chance to engage the new platform and UI, provide feedback on the Win8 forums, engage with Windows team engineers. It's called a "developer preview" for a reason!
The VC11 bits are well worth the download time - please download and give it a spin. Provide feedback. Now's the time!
@felix: way to go! Keep it up
