The Developer & Partner Evangelize team just posted a ton of new SQL Server and Business Intelligence content on Channel 9. You can check it out here - http://channel9.msdn.com/sql 

There are 22 screencasts posted as part of a developer training workshop built on SQL Server 2005 that has been delivered around the globe by Microsoft and Microsoft Partners. This training event takes the student through the Microsoft BI Platform giving a BI Developer the introduction and basic comfort needed to tackle a BI project using Microsoft technology.

I've heard great feedback from developers on this training. Glad that we're making this available broadly.
