This article on Gizmodo reports on a WSJ article about the discovery of this language. It is spoken by a small community in the Himalayas, where there is an abundance of dialects to begin with, but is unlike anything else the linguists have heard. They are extra-excited because of the notion that the language you speak alters the way you perceive the world, and these people therefore are believed to have a unique worldview untainted by influence from other languages. The WSJ article has text and audio examples of the language and everything. Add to all of this that, as Gizmodo points out, at least, the last speaker of an otherwise-extinct language dies every two weeks, and one can see how such a find is somewhat important. Plus, it gives writers new material for world building.
