Cyclone - new Cygnar heavy warjack with twin chain guns. Comes in a kit that can be used to make a Cyclone, Defender or Ironclad. Looks-wise it's my favourite of the new jacks.
Templar - new PoM heavy warjack, with shield and flail. Comes in a kit that can be used to make Vanquisher, Templar, or Crusader. Most boring of the new designs IMO.
Decimator - new Khador heavy warjack with a buzzsaw (sustained attack maybe?) and a revolver-style gun that sounds like it might have a knock-down effect. I like the design personally, not as much as a Cyclone though. The kit can be used to make a Decimator, Destroyer, Juggernaut, or Marauder.
Corruptor - new Cryx heavy warjack that sounds like it has toxic attacks (acid damage?) and denies souls to the enemy. Not a bad design overall IMO. The kit can be used to build a Corruptor, Reaper, or Slayer.
I dig the idea of kits that can be used to create different jacks, and have bits left over. I wonder about the cost though.
