I don't think an official title has come out yet for Japan. It's not impossible as Revenge of the Fallen was simply called "Transformers Revenge" in Japan though.
I can't wait for thor, captain america, Cowboys and aliens, Tf 3 Mission impossible 4 (Oh god) I hate tom cruise I really hate every film in 3D seriously why!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 2D is fine
Japan got the subtitle... so says on the official web site : Japanese Transformers: Dark Of The Moon Website Launched
