Mitch Wheat sent me this. According to http://www.microsoft.com/learning/mcp/certified.mspx, there are only 71 people in the world (well, at the end of June) who have achieved MCITP:BI. This means passing the two exams 70-445 and 70-446. You could be one if you use SSIS, SSAS, SSRS and do a bit of Data Mining. Doing some of the courses like the ones offered by Solid Quality Learning might help too, of course.
