It looks like honeymoon for Qlikview after Qliktech's IPO is over. In addition to Spotfire 3.2/Silver, now we have the 3rd great piece of software in form of Tableau 6. Tableau 6.0 released today (both 32-bit and 64-bit) with new in-memory data engine (very fast, say 67 millions of rows in 2 seconds) and quick data blending from multiple data sources while normalizing across them. Data Visualization Software available as a Server (with web browsers as free Clients) and as a Desktop (Pro for $1999, Personal for $999, Reader for free).
New Data Sources include local PowerPivot files(!), Aster Data ; new Data Connections include OData , (recently released) Windows Azure Marketplace Datamarket; Data Connection can be Direct/Live or to in-memory data engine. Tableau 6 does full or partial automatic data updates; supports parameters for calculations, what-if modeling, and selectability of Displaying fields in Chart's axis; combo charts of any pair of charts; has new project views, supports Motion Charts
(a la Hans Rosling) etc. Also see Ventana Research and comments by Tableau followers. This post can be expanded, since it is officially 1st day of release.
