I believe this is right, though your link came up for me as mobile so here's the standard version

http://www.amazon.com/Hobbit-Unexpected-Journey-Extended-UltraViolet/dp/B00E8S2JZ4/ref=sr_1_2?s=movies-tv&ie=UTF8&qid=1407164473&sr=1-2&keywords=the+hobbit

It looks like the 3-disc version is the one OP wants. One disc for the movie, 2 discs for the Appendices, just like from the LOTR sets. Ultraviolet is a code for a digital version of the movie, so ignore that.
