Whidbey newsgroups are available
It looks like there are newsgroups available for people with specific questions about Whidbey and related technologies. It's slightly hidden becuase it's not in the normal Microsoft.public.* newsgroup space, but there's web access (and instructions on how to use your favorite news reader if you prefer) at:
http://communities.microsoft.com/newsgroups/default.asp?icp=whidbey&slcid=us
So if you're having trouble with Whidbey features, fire away in the newsgroups! MSFT employees are encouraged to check them regularly and will respond to specific inquiries if they can :)
