In case Mark, Bill, or one of the other PASS attendees don't cover this in their blog...
and for good measure here is some more info about Yukon DTS beta 1 taken from Technet.
|re: Yukon DTS tidbit
Yes!! I don't use DTS much, but that new graphical debugging was pretty damn cool! But don't believe the article where it says "The new environment will be code-free...". Sure there may be a lot less code you have to write yourself, but there's still the place where custom code might come in handy. In the demo during the keynote this morning, he actually showed a bunch of .Net code that he had written for that "fuzzy lookup".
