If you look closely at pics from the trailer I found some on Konqrr's site and there are a few where it shows these dragon claws that are between spikes and it looks like they are holding items maybe this could possibly be a way to unlock items or a trigger that could be a weakness against the Dragon King. I just noticed them and I figured I would point them out just in case they meant anything but they could just be added details to the background. This is the link to the site http://konqrr.com/MKDe/Trailer03 if you look under the pics that MKD_T3_DragonKing_(then the pic number)you can see the claws in those this game looks like its gonna be an amazing game and could possibly be the best MK.
