On the “April New Release Information” page of Shueisha’s “Comics News” site, there is a listing for a “Neko Majin” kanzenban (complete edition manga) by Akira Toriyama scheduled for 04 April 2005.

There is no word on what is in it, but since it is a kanzenban, it is probably the entire series to-date. No price has been announced yet, but one would assume it will be close to the Dragon Ball kanzenban releases, which were ¥980 each.
