Thanks for Russell Christopher's blog, we now know that the final release of SQL Server 2005 Service Pack 2 is very close to going live. I will update this blog when the download link is known. I listed the SP2 major BI-related enhancements in this blog. The most significant ones (RS-SharePoint integration, enhanced Excel OLAP and data mining features) makes SP2 a major milestone in the Microsoft Business Intelligence roadmap.
