The folks at ERP Executive have a good article on the forthcoming name changes in the SAP Business Objects stack.  Have you gotten used to the "XI" moniker when describing the Business Objects version?  It is no more as of release 4.0.  The name "Xcelsius" has also gone by the wayside as SAP continues to innovate the product away from its Excel based roots.  The tool is now called "SAP BusinessObjects Dashboard".  The long awaited Voyager and BEx Query Analyzer replacement (code named Pioneer for a long time) is not going to get the name we long though.  Instead of SAP Advanced Analysis it is simply called "SAP BusinessObjects Analysis".  As soon as we have the full list of product nomenclature we will be sure to post it here!
