There will be little or no information before Bungie Day 2012. The first people to receive any information will be the people who received the Golden Tickets. A few weeks after Bungie Day, there will be an announcement of some sort (most likely a teaser or other similar way of releasing information). A few months to a year after this teaser, they will announce the game and everyone will bask in its glory.
