Thanks for my good friend Lorenzo Barbieri, I see that Microsoft has at long last released details of the new certifications. See http://www.microsoft.com/learning/mcp/newgen/
In the FAQ, you can see that MS have taken trouble to avoid actually saying that the current certs are dead, have no life and are now just being swept away. While you'll still be an MCSD, etc - those certs are no longer much use, since MS will be evangelising the new certs vs the older ones.
