Most amazing if they can make the dating stand up. This is the area where one would expect to find Indo-European culture developing, if one of the main theories of human language/culture development is correct, so this is huge really for that.
Gobekli Tepe has already re-written the textbooks on ideas of when humans began to shift into settled communities, and the ability to order a labour force to create something of significant size, so there's plenty of room for other things to chip away at once established ideas.
Very exciting, but they need to establish the dating first. So far it's guesswork from everything I've seen, and evidence has to drive theory.
