They released them out here today. The staff at GW are raving about them, claiming them to be some kind of wonder material. They claim you can have a fully assembled Azhag, drop it from 3 feet up, and it won't break at all(of course they didn't have the model to prove it). They also claim that Bloodtakers sword can bend quite a bit without breaking. Have yet to see any proof of these claims.
I also love how they call it the new range. Besides the material, it's all the old models, so it's basically false advertising, which last I checked was illegal in this country. I asked if I could buy the old metal models from the web store, and they said that anything that has been replaced, is now only available as finecast(I guess they melt the old models down and sell the giant mass of pewter to someone.
I miss the good old days, back before GW turned into a money-making monster. Or at least that's how it seemed when I started playing.
