Shueisha has recently updated it’s s-manga website with some new information about upcoming Ultimo and Jumbor releases. The following has been updated:

Ultimo volume 4 (機巧童子ULTIMO　4巻)
New release date:  August 4th, 2010
Old release date: July 4th, 2010
Price: 460yen

Jumbor Kanzenban volume 1 (ユンボル 完全版　上)
Release date: August 4th, 2010
Price: 490yen

Jumbor Kanzenban volume 2 (ユンボル 完全版　下)
Release date: August 4th, 2010
Price: 490yen

As reported earlier, these two reprint volumes of the Jumbor series are known as the “Security Editions.” However, on s-manga, they are listed as kanzenban, or “Complete Editions.” Shaman King also had kanzenban releases, but they were referred to as “Kang Zeng Bang.” The two Jumbor reprint volumes are referred to as “Up” and “Down,” instead of volume numbers.  We may have additional information about all of these releases in upcoming Ultra Jump and JumpSQ magazine issues.
