I also have various "understandings" of the status of OWB, but many of these understandings probably conflict with each other , this is one of the reasons that I was not volunteering to update wiki, rather suggesting someone from CA should do it!
...and while they are at it, they could create* a "Clarity" wiki-page, "CA Clarity PPM" is notable by its lack of appearance/links in wikipedia lists of PPM software, unlike many if its competitor products. (The key thing being to not make any page look like an advert, just a cited-statement of facts)
* - actually recreate ; there used to be one but some over-zealous wikipedia editor removed it a while ago!
