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
