Despite the Performance Point setbacks, Microsoft BI marches forward. The latest cool tool is also free. Microsoft has released its Data Mining Add In for SQL Server. While not necessarily GP specific it should work just fine against GP databases and cubes. I could spend a whole bunch of bits here telling you about it but why don't you just go here and see for your self how cool this is.
One caveat, this requires Office 2007 and SQL Server 2008 so some of you may not be ready for it yet.
