Teh Internets is awash with news of an Imperial Guard leak from the Games Workshop French website. They posted up summaries from the new codex and although they were taken down very quickly, they have surfaced on numerous websites and forums. I read all about it over on Warseer.
Speaking of Imperial Guard, I have posted up a battle report on my other blog. It's yet another game against Gary's Chaos Space Marines. Haven't they got the idea yet? You're not welcome in the Skolarii Sector!
