There are now leaked images out in German, and we are seeing quite a few more pictures of the new models along with the release schedule for pre-orders this week. The two primary model releases this week are the Electro-Priest box set, and the Tech-Priest Dominus. The Tech-Priest really looks like a fantastic model, and if the weapon options are also in the clampack, it will be quite a nice purchase.
Here are some links to the new images.
