I'm not merely going to say that we can expect the movie to hit theaters in 2012, I'm calling the release date,
December 21, 2012, Why?
-- It's the last Friday before Christmas, in the States that's when Christmas break begins in virtually all school districts. It's a great time to release a movie, two solid weeks of free time gives a movie plenty of opportunites to bring in theater-goers. Just look at
Avatar, it was released on the Dec. 18, 2009 - the last Friday before Christmas and the second weekend's take had scarecely fallen from the opening weekend's (not even 2%).
-- The Mayan long count calender ends on Dec. 21, 2012; I'm sure you've seen a special or three on one of the Discovery Channels or the History Channel. I expect we'll see more shows & specials in increasing frequency over the next couple of years and the channels are taking every opportunity to make sure most everyone is aware of the date. Legendary Pictures has an excellent opportunity to take advantage of some free advertising "groundwork".
The Mayan calender's ending makes for great story fodder all by itself, and the Godzilla movie can also take advantage of disaster/big change aspects of the calender's ending like few stories could. Add in an ARG (Alternate Reality Game, such as the one used for
The Dark Knight) along with regular advertising that also takes advantage of the calender connection and LP could build a lot of interest.
