Yes "The Progress Company" is making a lot of acquisitions. But OpenEdge is nothing more than a re-branding of the existing "Progress" product line. It has all of the same bits and pieces -- sometimes with a slightly different spin but it's all the same stuff and it does just what it has always done. Plus what you would expect in the "new" department that goes along with a major new release.
All of the acquired companies are still operating as themselves -- none of them have been merged into the OpenEdge product. Sonic is still Sonic, Data Direct is still Data Direct, Apama is still Apama and so on and so forth... Ok, ObjectStore got sort of renamed to "Real Time Division" but the previous owner had pretty well screwed up the "ObjectStore" name before PSC bought them so that doesn't really count. And yes, some of the acquistions fail and go away and yes, sometimes bits and pieces cross over between companies. And occasionally a phoenix rises from the ashes somewhere. But there is no wholesale blending of products going on.
At least not in the short term. We'll just have to wait and see if there's a master strategy in the long term.
