Google confirmed a minor Panda tweak on Nov 19, but so far no webmaster reports or Google confirmations for this past Tuesday. There have been a few lost rankings reports around the web, but no reason I can see to say it was a Panda iteration. Every algo tweak isn't Panda, after all ;)
I assume you're talking about this thread [google.com]. I noticed with some interest a post that says "Word on the streets is also that Google News did a sweep of sites that aren't really news sites. They completely removed the sites from their news."
