Quite a few new models can be seen in one single pic that is from the new "How to Paint Citadel Miniatures Orks: Morkanaut. On the photo we get a good look some new big guns, a look at the new meganob, and what looks like a new model for a Weirdboy in robes.
Please remember that these are leaked images, and that as such must still be considered rumors until we have an official launch. From this though we can assume that next weekend on June 7th the following new models will go up for pre-orders. Right now we are just looking for the final details of this Ork release.
Big Gunz/ dual kit
Meganob (Possibly a dual kit)
Flash Gitz (possibly a dual kit?)
