IBM's announcement this week of its intention to acquire SPSS was very interesting.  After all the consolidation a couple of years ago in the BI space with Hyperion, Business Objects, and Cognos all being acquired, this could mark a new round of consolidation.  Good timing too since stock prices are down due to the recession.  eWeek had an interesting article this week on the SPSS acquisition which is worth a quick read:  The article indicates that this acquisition really strengthens IBM and puts Oracle, SAP, and SAS on notice.
