Stephen Swoyer at TDWI wrote a good piece on Microsoft’s acquisition of DATAllegro entitled "Analysis: What’s Behind Microsoft’s DATAllegro Acquisition?" http://www.tdwi.org/News/display.aspx?ID=9056. Definitely worth a read. I too expect Microsoft to say more at their BI Conference which runs from October 6-8 and is located in Seattle http://www.microsoft.com/bi/conference/. I went to the first conference last year and found it gave good insight into Microsoft’s BI directions. I expect there will be much more this year especially now that PPS is a shipping product.
