I am also eagerly awaiting this feature but I've been told that the version its including in isn't due for release until Q4 2010
The official word from Support........
"Version 8.0 does not support WIM image provisioning. With the 8.0 provisioning frame work there is not a current work around to achieve this. With the upcoming 8.1 release WIM provisioning will be a supported feature."
is 2010Q4 the expected release date for 8.1 ??
Do we know if this was ever implemented? It would be great to be able to push an updated 2008 server WIM image instead of an outdated one and having to catch it backup as far as updates and other patching goes.
this is available in 8.1.
