Fathom was already well in the $1000+ range when those playfields were produced. They shipped in late 2004, IIRC, and an RGP search would show asking prices in that range in the entire year prior. It saw a price surge that year along with a few other machines, in part in anticipation of the new playfields, but not entirely. The playfields were in response to the rising demand and prices, too, so it was a two way street there.
