Some say Stormtrooper Commander is 30 (maybe 25), while Scout Trooper with Seeder is 60 (maybe 50-55).
Stormtrooper Commander looks to have the same paldron plastic as the Death Trooper, but a different color and print. Without it, it can work as a regular Stormtrooper. It has the same armor design placement and choice as the Death Trooper, now all in white with new head and different blaster design.
Now the Scout trooper has a similar armor design and choice as the Shore Trooper (specifically the scrit plastic thing now in black color), but the lower leg armor is one large armor shell + new armor add on revealed with the new Rogue One sets instead of the regular lower leg shell use to the SW constraction sets. The Vehicle looks descent enough, the center thing where the figure sits has the blaster integrate in it. The figure also has a small blaster rifle made out of small liftarm and axel pieces similar to the Death Trooper one. It also has a burnt orange color scheme for the technic (the small plates seen in the K2SO sets chest and the slight larger variant) and system parts on the vehicle (a lot of burnt orange slope pieces), while the other color scheme for the giant brick technic beams is ether light bluish grey, light grey or some other grey variant. It has two very visible plue pins where the hands connect to the speeder which arent an issue when the figure is connected to the set. Its also able to be held like a gun and swished around the room by the help of a technic liftarm skeleton underneath the speeder body (which I assume the technic liftarms are in a black color, possibly the same grey color as previously mentioned, the promotional art tends to change the color of these things for the effect). It uses both technic (the structure and some shapes), CCBS (primarily the figure), and system (for some distinct details) heavly for the design of this set.
Not sure how succesful this wave is gonna be due to the price and small amount of sets released (well only two for this wave), but the figures are definitely army builder worthy and I can see people buying multiples of them if they in the heat of collecting that sorta craze. The speeder is usable outside of the SW constraction figures (specifically if you want Pohatu to have his own speeder).
Plus it has a Chopper head recolored in black without printing on the hilt of the speeder.
PS: No SW: The Last Jedi sets were revealed in any of the leaks, kinda weird.
