I know we will have the official date in 1 hour when the conference begins but as I watched the new trailer for Battlefield 4 it now reads:

PREPARE 4 BATTLE OCTOBER 31ST 2013


Could that mean the release date for the PS4? The original date for the game is 29th for current gen which is a Tuesday, the day all games for current gen are released.

If the date is not right, please feel free to delete this post after the conference, just figured this might be hinting a bit.
