Announced today at their panel at Sakura-Con in Seattle, Washington, Yen Press graced the KINGDOM HEARTS community with some fantastic news: that they'd be resuming the publication of Shiro Amano's beloved manga adaptation of the series!
Those of you who are familiar with it may remember that Tokyopop had originally taken the Kingdom Hearts manga under its wing with the release of the first volume on October 11, 2005. They released all four volumes of the original KINGDOM HEARTS, both of CHAIN OF MEMORIES and the first two volumes of KINGDOM HEARTS II until 2008, when they abruptly ceased publication.
Instead of picking up where they left off, Yen Press revealed that they would be starting over anew. The release of the two volumes of KINGDOM HEARTS FINAL MIX in May 2014 2013, with CHAIN OF MEMORIES following the next month as one volume in June 2014 2013. They've also revealed that they have the rights to both KINGDOM HEARTS II and 358/2 Days, and will release the first volume of 358/2 Days in November 2013, the first release of the series's manga adaptation under their supervision.
Update (4-1-2013): It appears that the publishing dates for KINGDOM HEARTS and CHAIN OF MEMORIES were reported incorrectly by Anime News Network. The transcript of the Yen Press panel at Sakura-Con 2013 shows that the two KINGDOM HEARTS FINAL MIX volumes will release May 2013 and CHAIN OF MEMORIES will follow June 2013!
Following CHAIN OF MEMORIES will be the KINGDOM HEARTS II manga, as well as the KINGDOM HEARTS Artbook which contains illustrations by manga artist Shiro Amano. All of this will lead in to the release of 358/2 Days in November. Thanks to forum member lys for the tip!
Update 2 (4-5-2013): Shiro Amano: The Artwork of KINGDOM HEARTS will be released October 29th for $25 USD.
