As someone who's favorite system is the N64 and owns the NTSC N64 library CIB, I've already sold 1 of my 2 copies through forums. And could quite possibly sell the 2nd in the very near future. So that should tell you where I expect the price to go on this one.

It's just hot right now because it got publicity and everyone has to have it. It'll cool off soon enough and people will go back to not caring. You'll also see a wave of people trying to unload their dupes which is already happening. Those BINs will drop, don't worry.
