I ordered a 3G Paperwhite on September 11, and until today the expected delivery was Oct. 17. Today, however, I received an update, pushing it to Oct. 25.
I'm very tempted to cancel it and instead order through Amazon UK. (I'm in Switzerland and was planning to have it forwarded through Borderlinx.)
(At Amazon UK they claim that they'll start shipping on the 25th, but once you go through the ordering procedure it changes to Nov.12.)
