Sorry for the delay, I was hanging on for at least one image.
Introducing...
Kaito Sentai Lupinranger VS Keisatsu Sentai Patoranger
What we seem to know so far:
Lupinranger are the trio on the right (with capes). They are named after their colour: LupinRed, LupinBlue, LupinYellow. Yellow is a girl but the suit does not have a skirt.
Patoranger are the trio on the left (with police badges on their foreheads). They have numerical designations: PatorenIchigo (#1, red), PatorenNigo (#2, green), and PatorenSango (#3, pink). Though barely visible in this image, pink does have a skirt.
Both teams use the same transformation device, which are the guns they are all shown wielding. In addition, the Lupinrangers have a sword that can change into a grabbing arm. The Patorangers have police batons that can become megaphones.
Which ranger you transform into depends upon what collectable is attached to the gun. The collectables are generally known as VS Vehicles, or VSVs for short. The Lupinrangers will be using the little planes, which are called Dial Fighters and attach on top of the barrel. The Patorangers use the little cars, which are called Trigger Machines and attach underneath the gun barrel.
Each team can create a combined gun by combining their transformation guns and their three VSVs. In addition, the Lupinrangers have a final attack where they split into multiple copies of themselves. The Patorangers have a final attack where they merge into a single, more powerful being.
The VSVs are also their individual mechs. I think it's a ToQger type situation where their trains looked like the ones they used to transform with, but I've seen conflicting rumours as to how it will work.
There is a carrier mech called the GoodStriker. It is big enough to store six vehicles - the initial three for both teams. The GoodStriker will then combine with either the three Dial Fighters to form LupinKaizer or with the three Trigger Machines to form PatoKaizer. This means that only one team can form a combined mecha at any one time.
