The stated date was "end of October", right? In that case, I'd bet that the update will be released next Tuesday, the 29th. Gives them a chance to get past the weekend issues on Monday, and a few days left in the week to handle all the support calls that come in from the new update. With Thursday being Halloween, I doubt they would release it then. It's not an official holiday, but so many companies have contests and parties that it's not a good idea to schedule a major release on that day. Of course, this assumes that they still plan on releasing the update this month.
