Kevin has all the details - I must say I never thought I'd see these guys selling up and joining Microsoft but I'm glad they are onboard, welcome Mark and Bryce.  I've used the tools from for years, they are some of the first things I download to all my systems - amazing!  I'm looking forward to seeing FileMon, RegMon and Process Explorer in the OS (my top 3 - which are yours?), you never know it might happen?
