I'm going to guess a layout similar to current 4WD OffRoad buggies. Centralized Spur w/ motor mounted off front of the mount. Electronics in the rear. Possibly some new-fangled CenterGearbox to push motor (as well as Battery) as far to the center as possible. For grins, let's speculate a gearbox similar to that on the VBC Fwd car. (Which takes a page from the Tamiya M0# series of 'mini' cars but is more compact).. just because Tamiya likes to try things different..
Still waiting with baited breath.

off-set shaft would work for either the front or the rear gearbox, but not both.. unless one (bot not both) of those gearboxes has an additional idler (oldschool Tamiya) to give the proper axle rotation at the wheels. assuming they would use current crown gear design.
that's the beauty of a central shaft, just flip the diff gear to the other side in the gearbox, no idler needed.

Some interesting take aways -
The biggest thing I'm wondering now is seriously how is the thing going to stop bending/flexing front to back without an upper deck ...
And I still hope there's some metal crown/bevel gears in those gearboxes
- Car does look like drive chain is modeled after shaft driven 4-wheelers. Makes sense as it would make changing spur gear much easier. Inputs into the gearboxes are on CVDs - Plus!!
- Mid/Front motored - more weight shifted forward!\
- Alum/Metal gear boxes ... major plus!! And looks like there's lexan covers over the top.
- One piece servo holder
- Short shocks - joining the majority. I'll leave it to your personal preference on whether this is a good thing or not
- Surprised there's no upper deck. I wonder what is really keeping the chassis together

Don't forget the ínverted posts for the steering assembly, like f.i. the SP-F1 below.
Wondering same thing on the stiffenes, seems to be alu/metal chassis, this could help.
