I have attended VirtualTechDays Events which is organized by Microsoft on 9th & 10th April which was about the three products
1)Windows Server 2008
2)Microsoft SQL Server 2008
3)Microsoft Visual Studio 2008.
It was amazing. There were 32 sessions. Each session is of 1:30 hrs.
You can download video and Power Point slides from here.
