Trekmovie has a nice schedule with all the upcoming movies:
http://trekmovie.com/2011/07/28/paramou ... -date-yet/I think that Trek would fit nicely on November 30, 2012 between Bond 23 (!!!
) and the Hobbit, however that will definitely affect the box office as the Hobbit will obviously destroy all competition and I guess the studios know this. So, if Paramount plans with the $$$ in mind, they might try for May 31, 2013 which is a month after Iron Man 3 and a couple of weeks before Superman's reboot, so it would be quite a safe bet.
Of course, this means that we will have to wait ~2 years for the next Trek...
