Probably. There were a bunch of people propping up prices when they first came out as they looked for the exact heirloom they wanted. A lot of people found what they were looking for adn a lot of people way overpayed (750K+) for heirlooms thinking prices could only go up (kind of like the real estate bubble), but the fundamental buyers have mostly disappeared so eventually prices will have to correct to the uninflated market rate or just not sell at all.
