During FUNimations panel at Sakuracon, they were asked about the new Dragon Ball Z movie Battle of Gods. In a nutshell, FUNi said all Dragon Ball Z movies go to 20th Century FOX first since they still own the rights to create and distribute Dragon Ball movies and if they decide not to dub it then it will go to them, FUNimation. They also estimate that it will take about two years for this movie to get dubbed and come to North America.
