I am toying around with starting up a Guard army and after having my troops vaporised by Jesters Forgeworld Executioner turret I can tell you that I will definitely be picking some of these up if they come out in plastic.
Also on this page you can see part of an Ork Trukk. Is this part of the Battlewagon Upgrade sprue or the rumored new Ork Vehicle?
I will poke around and see if I can come up with some better shots of this image.
