I know that retailers release date's are usually unreliable, but when Stick Skills contacted Rockstar, the retailer replied with:

Thank you for your recent enquiry regarding the release date of Max Payne 3. Please be advised that the release date for this item, currently scheduled for 30/10/09, has been given to us by the developers of the game.

It looks like the release date is official. Payne Killers cannot confidently say this, but from the looks of it, November 30th, 2009 is the release date.
