For those who are upset that the poll shows Cinnamon as the (user) DE of choice, it always pays to read the latest entries on the Linux Mint blog. It doesn't matter whether Cinnamon becomes the default desktop or not as Clem intends to release two
LM 13 editions, one with the Cinnamon DE (Cinnamon is a fork of gnome-shell and runs on Gnome 3) and the other with the MATE DE (which is a fork of Gnome 2.3). Here's the quote from the blog:
Linux Mint 13 should feature separate editions for MATE and Cinnamon. Whether one of these and which of these two editions will be considered the “default” wasn’t decided yet.
Again, it doesn't matter which "edition" is chosen as the default "Main Edition". Both will be offered so you can chose whichever edition you want. And for for those of you who are wondering about the "the fate" of MATE or Cinnamon it stands to reason that since both editions will be based on the Ubuntu 12.04 LTS release that both MATE and Cinnamon should be supported for 5 years (EOL for 12.04 is April, 2017*) which is the length of time Ubuntu now supports it's LTS releases. It really doesn't make much sense to drop the DEs before the EOL of 12.04. Improve them, yes but drop them in favor of something else? Same goes for KDE. Folks who prefer KDE will have to wait a bit longer for LM 13 KDE to be released but it will be released and it will be an LTS as well.
I know the world of DEs has become rather uncomfortable since Gnome ditched the traditional desktop, I feel it myself, but for those folks who are considering dropping Mint because of this, well, that's your prerogative of course. However, this DE debacle is affecting every popular distro out there so you may not find anything better or more comfortable or more user friendly but that's up to you. This is just my opinion of course.
