I did not know where to post this one...
I am a Nintendo NES collector, and a topic that comes up regularly is "when will the price bubble burst"? Currently high end games are as expensive as ever and there still there is nothing indicating a crash of the market soon.
That being said, I was watching a popular podcast (Pat the NES Punk) commenting that, for example, Elvis collectibles were hot in the 80's-90's but as Elvis original fans got older and died off, the market of those items crashed, since new collectors were not filling the gaps left by the original ones.
My question to you is: have you seen this happen with Atari and the older consoles? Do new collectors replace the older ones? What can we expect for say, NES collecting in your opinion?
