Quoted from ledge:frenzy can dissipate into other interests, realisation that the roof needs fixing, kids need their school fees paid, other available pins... its usually what happens when theres an announcement. would you pay 12k for an original?
+1. Probably also like: wife's medical bill, buying a new house/car, brother needs money to get bailed out of jail, lost the day job, need fund for a new business, a ring, a vacation, a funeral...etc. Most of all, people may just buy the latest and greatest at that time and wait for the HUO BBBr (if happens) pop up down the road.
