Flickr User hinckley39 has uploaded tons of City, Ninjago and Hero Factory 2013 sets. I believe the original source is from the Swiss Toy Shop Thali that Brickset reported (but the site is now down at the moment probably due to overload).
This appears to be the final LEGO Ninjago wave with “The Final Battle”. Six sets will be released and features quite a few golden Ninjas and dragons.
