Last night (here in Europe) I started to receive notices about SQL Server 2008 R2 CTP3 being available for MSDN/Technet customers. Among the list of nice features (especially surrounding PowerPivot and SSRS see Teo's nice summary here) is the first release of SQL Server Master Data Services. I'm especially interested in the fuzzy matching and data cleansing features, but for a complete view reference the CTP3 BOL and the whitepapers on the SQL Server MDS site.
