You would hope that old EMD's would be grandfathered out of this update. My domain dates back to 1999, back when being an EMD was "the big thing"!
My domain is "word1word2" dot com, but I still rank #1 for the "word1"+"word2" search, and many related, so I'm guessing I'm good, for now.
Seeing that I'm still good in the serps, I can assume the site is not considered "low quality", which is good too. Hmmm, positive feedback evidence?
I have an EMD that has been around since 2000 and saw a 10 page drop on main kw's and I would not consider it a low quality site by any means. Hopefully you are not affected, but it could also be it hasn't rolled around to everyone yet as well...
