I'm sure you already know the answer to how this will turn out. The price will be substantially discounted. I notice that the secondary market isn't making headlines, just these initial sales.
> Ownership of a Fortnite skin guarantees that only the owner can wear the skin.
Is that guarantee in the cryptographic sense or policy sense?
Ownership in a "good enough to dictate the value of the object through its exclusivity." If the player base sees Fortnite renege on its promise of uniqueness, they'll revolt, or at least the price of these unique items will drop.
I'm interested to know how prices for tradable goods changed as they are obsoleted by newer, shinier things, or by the game being abandoned altogether.
