Thanks, Sergey. Google led me to Lumigent with its Log Explorer 3.0 as mentioned in your link:

http://www.lumigent.com

Based on Google hits it seems to be the leader in the category.

I also found NetIQ http://www.netiq.com which seems to base its analysis tool on Lumigent's

CA offers Platinum Log Analyzer http://www.platinum.com/products/dba/lasyb_ps.htm

Cyrano Workbench http://www.cyrano.com Seems to be aimed at performance analysis/tuning rather than detailed log analysis

BMC Software has announced a partnership with Microsoft for advanced SQL Server management, but I don't see any specific products listed - either it's consulting, or vapourware at this point.
