Well it looks like I no longer have to answer the question "when will Microsoft Deployment be released?" with the response "sometime soon :)".
Microsoft Deployment is now released!!
I wont go into all the details of what MDT does, you will find that information in many blogs (including my previous and future posts) and within the MDT documentation itself. Instead I would simply congratulate the development team for producing a worthy successor to BDD.
If you want to download MDT then you will find it here.
