I ask all those affected a little cooperation to make this experiment. Just 2 minutes of your life.
1) Check your keywords stats with this tool: (change example.com for your domain)
2) Make an screenshot since 17th of november and post the link here.
This is my screenshot:
As you can see I'm losing lot of keywords every day. My traffic has dropped 20% since 17th of November. Now my traffic seems stable, but with 20% less.
Do you have the same behavior? Are you losing keywords? Check it!
