Why would they ever do that? All of these steps of releasing a game happen in sequence, a sequence that is known and planned for. Only way it wouldn't "go gold" at the time they expected, would be if there was a massive problem. So, this fits with their planned release date.
(Also, when you have a massive advertising/distribution/marketing system, you don't just push a release date forward. They've been telling people Nov 10 for months now, retailers have their shipments scheduled, promotions & events like "midnight release" are scheduled, etc.)
...plus there's the part where they now have to manufacture all the discs, pack them up, and ship them.
Yeah. Gone gold? Whatever.
