One thing that surprises me is that Zane doesn't have any sets with his name in them. However, set names can be unreliable for telling you the set's actual contents-- if you were to look at the set names for this year's Ninjago sets without knowing their contents, you might think there was no set with a fire dragon, and no spinner set for Jay or Frakjaw. It could be that Zane will have a vehicle in some set facing off against the snake people in a set that has their name and not his-- or, alternatively, he may not have any vehicles until the second wave, since I doubt a theme so successful would not have a summer wave planned.
I'm kind of curious what the ninja minifigures will be like in this theme. Will they wear their normal outfits or DX outfits from this year? Will they start out in already-existing outfits, and then get new outfits later, just as the ninjas this year started in the normal outfits and moved on to the DX outfits? Or will they start out with brand-new outfits to keep the character designs fresh?
Anyway, I would really like to see some elemental weapons for our ninjas- like for Zane, something trnas-blue, and for Kai, trans-red etc.
As far as our protagonist's outfits goes, I'm hoping to see something new- something that shows they've graduated and are masters of their art. Perhaps a gold printing of their elemental insignia?
Whatever happens, I really hope they lose the whole names-on-the-backs-of-their-robes dealio. It makes it very hard to use those awesome dragon torsos for anything else.
