In response to requests from publishers, who were likely getting rather miffed at having their game's revealed outside of their plans for such, the ESRB is now offering the ability for games to appear on their site at specified dates. Now, when a publisher submits a game for rating they can fill in a box for the date it will see upload to the main ESRB page. While it was noted that "the ESRB system will not work for consumers if publishers arbitrarily select dates bearing no reasonable relationship to consumer interest in the product," we doubt if there is going to any publisher who doesn't take advantage of the new system and hold back ratings till the latest date possible.
Oh well. Thankfully, we still have other countries ratings boards to leak our video game info for us.
