De-emphasis? What are you talking about? .NET is a first class citizen in Windows 8.... I don't understand how this thinking has emerged. For one thing, it's wrong. For another, it's wrong....
IMHO its the result of the secrecy policy of Sinofsky about Windows 8. Giving a little bit of message once a while and keep mouth shut when people are in doubt and having questions, its very frustrating and kills trusts and confidence.
