Forum member zak001 informs us that the 6 new LEGO Hobbit sets are now listed at LEGO Shop at Home North America (USA | Canada). Product descriptions, pictures and MSRPs are available on each individual product page. However, you can’t order them yet.
Expected release date will be on November 27. Unfortunately, this also means that you won’t be able to get these sets with the LEGO Black Friday/Cyber Monday promotions as that ends on November 26 (how ironic!).
