The Transformers Vault

Another heads up to Transformers fan, a new item that might catch your interest is the soon to be released Transformers Vault: The Complete Transformers Universe

Now, to spare myself some time so I can get back to work on an animation, I'm going to simply quote Amazon.ca's description:
"For the first time ever, Transformers Vault reveals the complete story of the Transformers, everyone's favorite robots in disguise. Loaded with never-before-seen images, this book is a guide to the epic battle between the Autobots and Decepticons, as it began with toys and television, and continued to comics, film, games, and other media. There's something here for all generations, from classic toys that have become sought-after collectibles to the amazing, high-tech visuals of the three live-action films.

Hasbro has opened its official archives, gathering more than 250 images and several featured pieces of memorabilia. Look inside for a sheet of Generation One tech specs with a secret revealer, a rare pencil sketch from comics artist Casey Coller, an unseen character profile for Hot Rod from the 1986 film, an animation cel, and much more. Exclusive photos of Japanese Transformer prototypes, archival development art, and brand-new information about the future of the Transformers make this the ultimate package for every fan."

So yeah, looks very tempting.
