This refers to the third book in the Kingkiller Chronicles, even if it winds up being published under a different name. The question will resolve to the year the first readers actually receive their copies (physical or digital), not to any pre-order date.

Beta readers and any form of early access are excluded from this question. Any member of the public needs to be able to order a book and receive it for the question to resolve.

I will add additional years over time. If it becomes clear it will never be published this resolves to 'Other'.
