Quite some conclusions may be taken already from them, or at least some guessing for a few a cases.
So please, realize on the overlayed green circles and lines, in the previous images copies below, and respective comments also below. Click on the pictures, in order to get their full sized version and better visualization.
First, the obvious:
- V8 engine is included.
- Which new panels are used where, is now much clearer.
- Steering goes through HoG.
- Two LAs to control some crane sections.
- As realized on a previous post there are included just a few PF elements: The battery box, an M-motor and one Switch.
Followed by, the less obvious...:
-  Double driving ring gearbox on the truck left side, to handle 4 functions:
Two section articulations driven by the LAs.
The two other functions are not clear from this pictures, but imagine they could be: the crane turntable rotation, and stabilizers moving up and down.
- PF switch on the truck right side compartment, seems to switch direction of all movements controlled by the gearbox above mentioned.
- Both winch and boom extension/retraction seem to be controlled manually.
-  Some suspect, a new type of rack may be present into this set (either into stabilizers mechanism and boom extender mechanism too).
-  Some have also noticed there seems to be, two new types of studless TECHNIC frames, below and after the crane turntable, as well as on the rear axis (vertically mounted).
These seem to bring pin-holes in perpendicular directions, to larger beam pieces, which will means increased connections versatility for the system and stiffer structures.
From what can be seen, it seems there is an 'H' like formfactor version (probably 11x5) and another smaller rectangular one.
-  Also a new 'T-like' beam or connector piece, again increasing the options to easily build in orthogonal directions.
-  Some wonder what is a '16T Clutch Gear' doing in there. But guess it allows the gearbox to selectively transmit drive to both LAs under the limited space above the turntable.
-  Despite imagining a few possible reasons, also wonder what does another '16T Clutch Gear' here, attached to an 'axle 8 with stop' instead of a normal 16T gear with a standard axle.
-  And what is that, here? One LA bracket!?
Most likely yes, but quite unexpected.
TLG also didn't want to left the occasion goes by, without displaying a large scale version of this same model.
Overall, my impression from this set is increasing.
Every year's new parts are giving TECHNIC sets, more and more realism, while offering new building possibilities, functions and compactness.
Now the profit is back, it seems TLG also realized that always producing new parts, while keeping permanent control to the number of active elements, drives fans interest and potentially generates new sales.
Thanks Ryan, Martijn and Jo, for letting me know about these new photos.
