in a german video
there have been some information from a German Event, that were not in any other video.
According to the video, while using the left movement cross thing, you can change the facial expression of your skylanders. Also, they mention some of the movement
climp, stealth, rocket, speed, teleport,
And on oneof swords I found digging as a movement.
So we know 6 of 8 movements already.
And they said that two players can fly side by side in the swap zone. I wonder if you need both flying characters for that but probably not :)
Will keep you updated!
