I'm not sure what it means, but I'm guessing it isn't good for users of Retrospect. Dantz announced on October 12 that they have been acquired by EMC, the storage manufacturer.

There is an FAQ from Dantz, which says basically nothing about the issue.

However, an article from Bynkii.com details discussions with both EMC and Dantz that they may both understand the situation and be actively courting the Mac user base.
