We are returning to the Horus Heresy rumors as it appears the Horus Heresy will be a big thing coming this fall with a new box set and a whole lot of cool plastic kits. This sounds great and this little rumor bit just adds to the Spartan Tank saying that it will be a dual kit and the new miniature will not be a Lord of War option.
(paraphrased)- Rumored part is at minute 3:30
"The new plastic Spartan Tank will be a Dual Kit and the other option is not a Lord of War option."
"Horus Heresy new release is coming in October"
