That's disappointing to hear. I've seen Rothfuss at PAX and going to his panels he's an incredibly magnetic speaker and even watching him play D&D is a lot of fun, but having no resolution for this story kind of stings.
Wise Man's Fear felt far more aimless but I still really enjoy the kind of fantasy he tells, it's incredibly distinct from any other fantasy out there.
But damn... the sense of promise that The Name of The Winds had when I first read is head and shoulders above any other first entry in a fantasy series I've tried. The really human way that all the characters act and that things are written, the intrigue of the Chandrian and the great framing that leaves you wondering what crazy moments lie between Kvothe at the University and when he's an innkeeper... ugh that book was wonderful. After Wise Man's Fear, Rothfuss's comments about this trilogy maybe not even being the fully story arc, and the indefinite wait for Book 3, it's just hard to hold onto the excitement I felt coming off that first book.
