I found this out on Anime News Network and this actually quite awesome.
The original anime cast from the Ghost in the Shell films will be featured as the “dubbing cast” for the Japanese language version of the American film coming out later this month. Atsuko Tanaka will reprise her role as Major, Akio Ohtsuka as Batou, and Kouichi Yamadera as Togusa.
All three actors played these roles in all variations of the anime except the most recent projects, Ghost in the Shell: Arise and Ghost in the Shell: The New Movie.
Another announcement is that famous DJ Steve Aoki is doing a remix of the opening that was performed for the original anime for the film. A preview of it was posted to Youtube as a TV ad and a full version was posted as well. It actually sounds pretty amazing.
Ghost in the Shell stars Scarlett Johansson and opens March 31st.
