I don't watch anymore either, but I do still look forward to the Treehouse of Horrors every year.  Funny thing, when I went to the San Diego Comic Con in 2006, I sat in on the Simpsons/Futurama panel, and Groening said quite clearly, "We we never end the Simpsons."  Everyone was really happy about that in the panel...bet they aren't so happy these days.  I'm sure it was mostly a joke, but it was an interesting comment for him to make all the same.  

Even this song says it themselves.

I remember seeing a promo or trailer years ago about The Simpsons Movie, and they did a mockery of the show coming to an end.
