Shueisha has updated their listing for the JSAT Edition: Dragon Ball – Heya! Son Goku and Friends Return!! comic which is due out in Japan 03 September 2010 for ¥730 (~$8.00). It now lists some additional details that make this release much more intriguing than it ever was originally, as it appears this will not be a re-release of the manga adaptation drawn by Naho Ooishi in V-Jump. This new comic will be 160 pages in length, while the adaptation by Ooishi was only 72 pages which was slit into two 36 page volumes.
That said, all of the original film animation comics (or “animanga”) were between 150-165 pages in length. On top of that, this new comic will be the exact same size as the film animation comics, “New Book Format” (11 x 17 cm), and Toriyama is the only author listed.
I hate to say it, but it seems that this will simply be an animanga edition of the Jump Super Anime Tour special. On the positive side of things, many of the film comics did include tons of supplemental information, so hopefully we can look forward to that.
