Maybe, but I don't think so. The market is simply going through a cycle.

With such a high price per IP there are a lot of organizations finally putting in the effort of cleaning up their space and selling off blocks. I know a company that was doing consolidated and clean up for an aggregation of freeing 200k worth of space. They were looking at adding $15-35M to their pockets.

IPv6 support is still not where it needs to be. Look at the clouds. There are many services that still are only IPv4 or partial ipv6 support. Just check back in 1-3 years and the price will have recovered.
