Today Amazon.de has upload a ton of listings for various upcoming LEGO 2016 sets. There were many posts on Eurobricks on these listings but I’ve organized them alphabetically by theme. Thanks to CM4sci for the heads up. The set names are loosely translated from German so they might not be the official names but they give you an idea of what the sets are. This list does correspond to the list that came out a few days ago.
Update: LEGO has asked sites to remove the list. Amazon.de messed up and accidentally posted it just a little bit too early. Sorry folks.
