Bill Ramos, the PM for Management Studio, XM and a bunch of other stuff found this sample book chapter today, its got good coverage of the new features in the tools.
The authors obviously have some good inside contacts, the screen shots mostly refer to a machine called ThomRiz, this is the e-mail alias of Thomas Rizzo a Director of Product Management in SQL Server. He folllows the common(and recomended) practice of naming your machine after your e-mail alias, sometimes with a number following(after all there can only be one machine called Chewie on our domain and someone got in ahead of me) so it seems like a good plan. This means these shots came from Toms machine. Even more intriguing is the perfmon correlation demo thats coming from a machine called komododemo3, thats one of the tools team demo machines that lives in the lab! Not sure I want to know more :-)
