UK retail site PLAY has Max Payne 3 all set for an October 30, 2009 bullet-timed released. When Live Playstation followed up with the retail outlet for comment on where it got the date, the site was told the gaming chain was given the information by "the developers of the game."
We followed up with Rockstar Games -- the publisher -- and a representative stated it hasn't announced a release date. In fact, all the rep could do was refer us to the corporate announcement that the game was coming this winter. If things change, we'll be sure to update.
