It was a random coincidence that I came upon it then...and now Japan Probe has word that an animated series is in the works and is even being screened at the Tokyo Anime Fair. It's CG, as opposed the anime style we're used to, but holy god do I want to watch it.
“The concept of this work is the development of real and fierce combat by cute and fluffy animals. In these days when people have become too used to seeing people die in movies, we wish to use cute animals as the characters to give viewers a stronger feeling of the misery of the wars that are taking place in this world.”
ETA: As noted in the comments and at the Probe's source, Patrick Macias' blog, it's not a direct adaptation of the original story, but will feature characters who are members of a private military company.
Interesting. What say you, Vicers?
