Post fine-cast fiasco, Reaper are doing something similar now. Re-casting miniatures in a plastic-resin material.
The difference is... The reaper ones are a fraction of the price of their metals. Though I realise that GW's price rises were unrelated to the change-over, and we have yet to see how Reaper manages quality control... At $2 for an Ogre, this can't make GW them look good.
