Ground Zero Games has made the new releases from the Colours convention available to everyone:
Crusty Combat Walkers (link)
Resculpted NAC Power Armor (link)
Heavy Crusty Infantry in Environment Suits (link)
I know I'll be placing an order soon - I can easily put all three releases into immediate service. I'll use the Heavy Crusties as command teams for my current army. And if the new NAC PA minis are a taste of what's to eventually come for all Tuffleyverse factions, we'll be watching very closely.
