General facts - boxes are red and have Jay on them. Main collectable this time around appears to be some sort of dragon sword. New hilt with a stud on it (appears to have a cartoon ninja face) and two axe blades, those energy blades. The minifigures look the same as the summer ones but with a new shoulderpad and new torso prints.
70599 - Small brick built dragon, brown, sand green. Minifigures are Cole and a pirate with a green bandana, orange and brown outfit, and a new sword.
70600 - Two bikes, one for Kai, one for Nya. Nya's in her Water Ninja outfit, holding one of the new "dragon swords." Her bike has little water shooters. Bad guy is green bandana guy, with new sword and a jetpack that includes a trashbin that shoots flaming garbage and orange bits.
70601 - Sky Shark is a small flying vehicle. I see treasure chests inside the [thrusters/engine/whatever] chains, anchors on the ends of the wings, and orange blades (ones featured in 2012 in gold, the one with a bigger version too) Drops dynamite. I think it's Lloyd, but a ninja is included with what looks like a jetpack.
70602 - Wu Dragon-like dragon. Looks REALLY nice. Blue, white, dark blue, gold and black. Bad person is Toxikita? She comes with a little flyer with a 6 stud shooter (in the shape of a cone this time) and a dragon sword. She also comes with a monkey! (one from the old Pirate sets) monkey is grey with orange limbs (one is grey) and a brown stud shooter.
70603 - Really neat ship. It's like a smaller version of the Destiny's Bounty. Skull in front, cannon, anchor on side, steering wheel, etc. The "blimp" part is just the Friends air balloon in orange. Doesn't look to bad, honestly. Pirate flag in the back. Also included in the set is a small flyer with two of the old spinner tops on the sides, along with a stud shooter on each. Zane piloting, holding one of the 'dragon swords' The characters include Zane, a new samurai with dark green armor and orange clothes. Two of the new sword. Pilot is a green snake...which I find kind of weird. All these characters being mixed together. Then again, probably prelim.
70604 - Neat island. Two areas - one is a small rock structure that uses a drill piece as support. On top is a samurai big-fig wielding an anchor! Orange and dark green with a blue face, looks super cool. Also on the small area is a tree that looks really cool, uses a bush piece and has two orange minifig heads hanging from the top. A small wooden thing is used to walk up it. On the bottom of that is a grey/dark green ninja. I think it's Zane. The main part of the set looks sort of like the dojo/temple sets. I see those old ninja swords used on the rooftops. On the bottom is a small cave area with one of the 'dragon swords' protected by some teeth lookin' pieces. Some leaves, then the second 'floor' is just a window. Top is more roof. There's a small spider build included, has one of the 2013 Samurai helmet "crowns" in gold. Above the spider is Sensei Wu wearing a pilot's cap and is in a small hot air balloon! I love it! He is dropping the fruit on the trees onto the spider. Kai is swinging from a vine, and a green bandana guy appears once again with a jetpack made of PoTC bottles and the new sword pieces.
70605 - It's.. it's weird. Think GIANT brick-built animal head with big orange thrusters on the side, the mouth being a sort of landing area, and the top bit looking like the Alien Tripod from Alien Conquest without a dome. Pirate flag in the middle. The back has like two fins connected with something that looks like a spoiler on a car. On the landing area is Jay who is fighting a, and get this... a four armed ghost holding a dragon sword and a samurai sword. That minifig looks completely preliminary, but I'm curious to see how he'll turn out. Monkey appears again in a cockpit near the front. In the back is a spinning barrel with the green snake guy in it. There's a small bad guy flying vehicle with someone I can't make out in it. Orange. The ninja vehicle is an oddly BIG, BIG jetpack piloted by Lloyd who is wearing Space Marine armor in orange.
That's all I think I can make out! If you've got any questions, please ask!
