I agree that resin opens up some interesting possibilities. Although I am a little concerned we don't end up with things in resin that would have been significantly better done in plastic. This tank maybe an example of that. I'm trying to keep an open mind.
This allows Our Gracious Hosts to test the market for French tanks. If stuff is going to sell in sufficient quantities it is more economical to produce it in plastic. The moulds last much longer, the materials are easier to handle (and cheaper?) and there is a certain cachet to a plastic kit.
Remember these are a bought in product that has been given the Rubicon treatment.
I hope they make it to Warfare in November.
