Ownership of a Fortnite skin guarantees that only the owner can wear the skin. Owning an NFT doesn't guarantee exclusive use, as anyone can view the digital image/video/etc that the NFT has wrapped.
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.
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.

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.
An NFT doesn't say anything about the uniqueness of the underlying digital good, it only shows who owns it. That Fortnite skin can still be duplicated endlessly.
