Holy balls. Horus Heresy Book 1 – Autumn 2012. Can. Not. Wait.
The Games Day seminar seems to indicate that Primarch rules and miniatures will be in. Each book will focus on different parts of the Heresy to ensure every legion gets their moment in the spotlight. The trailer ends with the Eye of Horus, so much like the book series, it will start with the Luna Wolves/Sons of Horus. I can’t imagine Book 1 not covering Istvaan. Hopefully more details will emerge in the coming days and weeks.
