Getting back to the idea that Google is working on an algorithm fix....
From what I've seen, Google is not only working on a fix but has implemented some new code. Specifically, I'm seeing pages from my site that were affected largely bounce back. I'm also seeing the traffic curves in Google Analytics become more normal - my traffic usually appears as a pretty smooth sine wave, and I'm coming back to that after a period of what looks a bit like arrhythmia, particularly if I focus on the most affected content. The traffic level curves are also closing (or have closed) when I compare the past week to a recent, pre-update week of traffic.
The pages for which there remains a significant re-ranking effect resulting in a loss of traffic appear to be those that have a lot of text in common with other legitimate sites. I have a couple of forms on my site that used to get phenomenal traffic, but they're forms - they don't look much different from other versions of the same form and, beyond that, they've been so heavily "borrowed" by trusted sites that... they're everywhere. I have another article that goes through a complicated statute, and much of the text is comprised of quotations from the statute (albeit formatted to be much more clear) - and a state government agency reworked my article a few years ago and put it on its own website - so it doesn't look very unique. I don't expect these pages to bounce back to prior levels with their present content and... to the extent that Google is simply reconsidering how it ranks pages that are very similar in content, that's not unreasonable.
