FUNimation has released some information about the upcoming release of the ninth Dragon Ball Z movie:

Don’t forget the Dragon Ball Z movies, the special DBZ releases, and of course, DBGT The Lost Episodes! The DBZ movie, Bojack Unbound, is scheduled for release in August and DBGT The Lost Episodes will be available July. Stay tuned to www.dragonballz.com for all the latest news and information on your favorite animated action series.

Going with the name that has been on the trading / collectible card game (“Bojack Unbound”), we can apparently expect to see movie 9 released “sometime in August”, though RightStuf has the movie listed very concretely for release on 17 August 2004.
