I have updated the release list on the right with some new dates. (You might have to click into the calendar.)
GT's Creation and Proliferation are now June 3rd. (official date) Ramifications and Preparations are now July 15th. (also official)
That leaves 43 episodes not announced yet for DVD, including the 12 that were "skipped" in the beginning of the series.
Three new Dragonball box sets are also announced: Piccolo Jr. Part 1 (July 15), Part 2 (Aug 19), and General Blue (Sep 23). The Piccolo boxed sets go to the end of the series/beginning of DBZ. After General Blue, all DB eps will have been shown on TV or DVD. (There are four "sagas" remaining to be released, but have not yet been announced: "Red", "Baba", "Tien", and "Pilaf". The Pilaf saga is the first two that Funimation may not have rights to yet.) As a side note, the date for Piccolo Box #1 is now official.
DB movie #8 is announced for Aug 26, but no other DB announcements are made. Cell Games and Saiyaman still have received no releases on DVD, but are now all released on VHS. (Actually, one Cell Games DVD was released some time ago, but no followups.)
