Just heads up for anybody who missed it on Zee Internet: on Horus Heresy Weekender, Forgeworld presented ancestors of our beloved Imperial Guard, great Imperial Army. There are Hetze-ehm, Leman-chassis based Basilsks and Medusas, Malcador-chassis based Dracosan transport and Deep Space-esque Solarian Auxilia.

For images of those sweeties (and many more, after Shield of Humanity I guess those playing Crimson Guard will love tracked monster known as Triarios armoured transport), I recommend this blog http://recalcitrantdaze.blogspot.co.uk/

I do not want to be presumptuous, but I think these pieces of hardware will survive well into 41st Millennium for many gamer-groups.

yeah almost got nerdgasm when those pics where unveiled
forgeworld truly sets new standards every release

all thats missing now is a 40k Mechanicum codex altough my group doesnt mind me playing them with the horus heresy rules
