The market is dropping since last October... right from the moment some company told the world they were going to remake a certain title. Even close related titles lost value and even interest due to the announcement.
Not long after the price indications got removed from Pinside.
I do think that the introduction of a new line of 'LCD-pins' like WOZ + Hobbit, (maybe is Stern also heading that direction with their next title) will do no good for current (DMD) pricing.
