Quoted from Whysnow:
to me that makes sense.
Buy the LE on the secondary for a discount. The majority will drop dramatically. Some will go up.
IF it really is your dream theme then I can see shelling out for the LE. For example a Good friend really loves GB and has 2 young boys. He got in early on GBLE because he will never sell it and it is his first NIB experience. That makes sense, but he is buying with emotion and not with logic. Splurging on emotion is all good.
The bad/mediocre LEs may drop dramatically, but the decent/great games typically have a small dip within the first year, then return to at or above NIB pricing - used METLE, ACDCLE, TRONLE, SMLE, LOTRLE, TWDLE, STLE, WoZLE, etc are all at or above NIB pricing. I'm 100% positive GB will be in this category - there may be a *couple* of used LEs that sell under NIB pricing for 6-12 months after release, but then the prices will start to tick upward. And those few that do sell under NIB pricing will be snapped up really quickly...
