I wonder if this will be the inflection point in Sanderson's career, I can already hear the "everything sucks" critics sharpening their knives over the amount of money raised. He could drop something with the impact and longevity of "Lord of the Rings" and there's still gonna be people bitching about that much money for 4 books.
Another nail in the coffin of the traditional "publishing industry" too. Expecting to see "edited and produced by" credits in books soon, and to pay attention to the names of those as much as the authors.
