The Legends of Chima, as you possibly know, is one of the new 2013 sets and it will possibly substitute the 2011 Ninjago. According to the pictures below the rumors are highly supported because all the style, the feelings and most of all its features with all the gaming cards are quite similar for sure.
Basically the theme has two different concepts: the traditional sets with vehicles, figures or whatever and the speedorz that apparently will replace the Ninjago spinners. Some sites give a quick but not too detailed explanation about them talking about a sort of small vehicle with a pullback mechanism which will interact with the cards. Next year we will see about that.Talking about the sets, they are quite strange and different just as Ninjago was.
