As said on
BrickPirate in my natural language:
Get ready for the third jellybeans' batch, with colorful armors and hovershields which Marty McFly would be jealous of!
Maybe the new helm mold would have been interresting, but not in those colours it is introduced here, the visors although may add variety to any castle collection since their metallic look will match more realistic verse too.

Those guys at Lego seem to have come to "Le Puy du Fou" on their last holidays to copy the concept of the moving castle.

The book can be handheld by a minifig both closed and opened. At least it looks like it can.
If no other "classic" castle line is released beside this for the next three years, it won't hurt my budget much, which is good news, unless my son would want some for himself.

This will let me concentrate on the humans "castle" sets, and the '80/'90 Legoland castle ones.
As for the Ninjago, I would guess success will depend on how they catch the public attention with the background and storyline, and we know how well they did. There's no reason why they won't succeed, even if getting just pictures of the sets may leave us dubious about it.
Little baddies are quite fun, indeed.
