Reports are that the list of light novels to be published in December 2010 by Kadokawa from
The Sneaker Library (included in the next issue of
The Sneaker out next Saturday) has been leaked on 2ch. The list
does not include
Suzumiya Haruhi no Kyougaku meaning that the tenth novel will likely not be published this year as planned. Nothing has been mentioned about progress of the book so far.
Here's the link to the Yunakiti gathering of the 2ch posts.
