This is the most likely scenario: more supply and less demand results in depressed value.
On The Harbinger, prices are only down slightly. They usually float between 18k and 20k, just checked and the low price is 17099.
I think this is it too, augments prices also took a nose dive and have sold very slowly. Even MK-9 kits took a bit of a hit (pushing into the 59K range at one point) before coming back up yesterday, most likely as excess supplies dried up.
