I think the discontinuation already happened in 2010. I don't think they are discontinuing the remaining 6 in 2011. You can check the discontinued thread but it doesn't list the 6 left as being discontinued at all.
I was told that they are getting rid of some. My favorite artist at the store by my job told me some are on their last legs and some have already been cut. She said that she believes that they are keeping the more popular ones. I am still going to pay attention to them though because brown script is one of my all time favorite eyeshadows now.
