By way of Amiami's Rakutan store
we have confirmation that Takara-Tomy and Million Publishing will be releasing a new volume to their Transformers Generations book series. Generations 2012 which according to the link will be released on 18 April 2012 will feature an article on Transformers Prime, a complete listing of all Transformers Dark of the Moon toys, behind the scenes material and designer's interviews, and more. Best of all to myself at any rate is the promise of a comic titled "Masterforce - Another Story of Pretenders".
There will also be an exclusive toy mail away campaign offered in connection with the book - no word yet on who or what the exclusive might be.
