If one goes to the website linked above, an archive of the International Bear News is provided. Bringing up the November 2007 issue, page 6 offers an article entitled "The Ninth Bear," about the brown bears of Asia, especially southern Asia. The authors contend the yeti has been shown to be a brown bear, and use "the elusive and symbolic nature of the yeti" to discuss how poorly known these bears are. The authors don't rule out that this area might contain an actual ninth species of bear (in another issue of this publication, it's noted that the critically endangered Gobi Desert population is held by some to be a separate species from Urus arctos.)
Food for thought.
