The official Japanese site for Code of Princess has a link to the games official blog which I had no idea existed. Apparently they’ve released a complete Code of Princess art-book full of art, character/story info and sketches. The blog also has details the 2-Disc OST and a Code of Princess card game. The art-book is available at Amazon (JP). Dengeki also has some information on it. I barely know any Japanese, you guys figure it out.
