Hi Dirk,
From the changes rolled out primarily last week, no, I don't know of anyone. I do know, however, of numerous sites that are making big changes to their content presentation and structure such that they'll no longer display the problems we're thinking Panda-slapped sites have. That is, removing duplicate content (by any number of means), consolidating thin or duplicated pages, removing spun content, etc.
I'd check back in a few weeks after people have had time to get these changes in place, have Google crawl their sites and update rankings. In many ways, I think it' too early to tell where rankings are going to fall.
