The short answer is, it depends.
If we need to produce less than 300 copies (300 backers or less) we will produce everything in resin.
If we go much higher than that, it will be most efficient to produce our miniatures in metal. Metal miniatures will be produced by Iron Wind Metals, just like most of our other minis.
Large Monster models, however, will always be produced in resin. They are just easier to build and play with when they are resin.
