|Summer 2013 in fact.|
Also perhaps not so surprising, given it's the in thing; the next film will be released in 3D as well as 2D. 3D lens flares!!
In another confirmation of expectations, ComingSoon.net reports Michael Giacchino will be back to compose the score of the next film.
And the outcome of all this for me: I now have a 2013 schedule page with one thing listed on it!
