Monday will be the update. I can tell you for sure that it has not hit yet. I got back all my rankings, and I am really hoping I dont get smacked down on Monday.
I said earlier that I requested reinclusion in webmaster tools. I got a message back saying I was not manually penalized for anything. However they did include this;
Of course, there may be other issues with your site that affect your site's ranking. Google's computers determine the order of our search results using a series of formulas known as algorithms. We make hundreds of changes to our search algorithms each year, and we employ more than 200 different signals when ranking pages. As our algorithms change and as the web (including your site) changes, some fluctuation in ranking can happen as we make updates to present the best results to our users.
If you've experienced a change in ranking which you suspect may be more than a simple algorithm change, there are other things you may want to investigate as possible causes, such as a major change to your site's content, content management system, or server architecture. For example, a site may not rank well if your server stops serving pages to Googlebot, or if you've changed the URLs for a large portion of your site's pages. This article has a list of other potential reasons your site may not be doing well in search.
So while no manual action was taken, they are warning not to bug them about it because they make changes all the time. I hope you guys are tracking your rankings now because Monday could be your sites reckoning.
