Yes, they began to test it for some limited accounts about 1 month ago: http://forums.digitalpoint.com/showthread.php?t=159113 but now looks it is up for almost all accounts. Now they are testing a new exciting feature: The Quality Score Column for keywords - an additional column will show if the keyword quality score is low, med or good for each of your keywords - probably they will enable it until the end of the year.
Yeah I read a blog post about the quality score column earlier in the week, sounds like a great addition.
I thought I saw a blog post about this earlier in the week but I think I might be getting confused with the ad preview column.
I think that you are making confusion. I tried to search Google during some time and the only thing I found about "Quality Score Column" is this own thread. I know about this new feature because I have been invited by phone from Google to beta test it, but still received no update about it.
update: For those interested in the Quality Score Column (commented in this thread a long ago): http://forums.digitalpoint.com/showthread.php?t=204204
