Amazon listing appears for VIZ Media release of Adventures Black 2 & White 2 chapter
A listing has appeared on Amazon.com for "Pokémon Adventures: Black 2 & White 2 volume 1". Based on the volume's 200 page length, it is extremely likely that this will be an English version of the full-length Pokémon Adventures volume 52, which was released in Japan in December 2014. VIZ Media's English translation is due for release on January 3, 2017 (ISBN 1421584379).
This will be the first full-length Pokémon Adventures volume release by VIZ Media since the release of Pokémon Adventures volume 51 (titled as Pokémon Adventures: Black & White volume 6) in October 2015. All of VIZ Media's Pokémon Adventures releases in 2016 have been mini-volume length collections based on the magazine version of Pokémon Adventures.
With this volume, VIZ Media will have released all 52 full-length Pokémon Adventures currently available in Japan. It is not currently known when Volume 53 will be available in Japanese; as since 2015 Shogakukan has only published collections of the X & Y chapter and the Omega Ruby & Alpha Sapphire chapter based on the magazine version of Pokémon Adventures.
