Yesterday the MDT team in Redmond released MDT2010 to the web for download. There is a blog posting with the location for download here: http://blogs.technet.com/msdeployment/archive/2009/09/09/mdt-2010-is-released.aspx

Also Michael Niehaus did a great series of blog posts on most of the new features of MDT 2010. You can review those posts here: http://blogs.technet.com/mniehaus/search.aspx?q=MDT+2010+New+Feature&p=1
Make sure you review upgrade instructions for moving from earlier versions of MDT to this latest greatest one.
Happy Windows 7 Deploying!
