Need more info on integrated reporting controls

I am looking for more detail on these "integrated reporting controls" mentioned below (from http://www.microsoft.com/sql/2005/productinfo/top30features.asp#B):

"With SQL Server 2005, Reporting Services will provide report controls that will be shipped with Visual Studio 2005. Integrated reporting controls will provide improved reporting capabilities for enterprise applications".

Specifically, I am looking for more detail on these new ASP.NET 2005 controls that make dynamic server side reports generation via the Reporting Services Web Service easier.

Thanks.The Report Controls are described at http://whidbey.msdn.microsoft.com/library/?url=/library/en-us/rs_vsrpts/html/0334cfba-2cb7-4d8b-8927-e08b888450cd.asp?frame=true. They are not focused on report generation (this is via RDL and the XML library), rather report execution.
