The MDT Team has released the first Update to MDT 2008 (which is really the second update to MDT, hence the 4.2 version number). The main new features for this release are support for OEM preload scenarios (i.e. having the PC vendor preload an image onto your hardware that will work with MDT in your environment) and a revised System Center Operations Manager Management Pack. Minor updates include bug fixes and design changes to override driver platforms as well as the ability to inject all drivers into Windows PE. This release also has revised documentation.
I'm sure that once we've had a chance to give this update a thorough review, the Deployment Guys will have more to say about how this update will impact your deployments.
