Ninjago Spinjitzu set rumours

As we get closer to new Lego sets coming out, here is a list of Ninjago sets releasing:

71777 Kai Dragon Power Tornado Spinjitzu 

This set could be the return of the dragon form from last summer, just in a spinner set.

71778 Nya Dragon Power Drifting Spinjitzu 

Nya, on the other hand, did not have a dragon form, so this could be brand new.

71779 Lloyd Dragon Power Spinjitzu Cyclone 

Just like Nya, Lloyd did not receive a dragon form; he received an Oni form.
