It doesn`t matter if you are actuating the clutch with a cable system or a hydraulic system, it will require the same amount of pressure to disengage the clutch, and the same amount of effort at the lever.
The only advantage to the hydraulic system is that it is easy to route a hose through tight spots, but the cable needs nice big radius turns.
True same amount of pressure at the clutch, but less amount of pressure at the source (master cylinder) to push that pressure at the clutch. Hydraulics can be designed to require less source pressure than destination pressure. Simple example but it shows the idea
To me the pic doesnt look like a normal cable type clutch cable but that is just me.
As far as going back to a cable I think is a bad move. To me it's just cheap. Low cost entry level bikes I get but not on a Harley why take steps backwards.
As far as a cable with RDS system I don't think it will matter as to my knowledge there are no sensors in the current clutch set up. It all based off wheel speed lean angle braking and tire slipage

This is sort of true. The design in the example reduces force at the source by increasing the distance traveled. The same can be designed into a cable by mounting the cable attachment point farther away from the pivot at the base of the clutch lever.
The real gain is that there is less friction loss with a hydraulic fluid versus a cable. if the cable is perfectly straight, there is little friction. Once you incorporate the slightest bend, the friction builds fast.
At least they made it kinda nice. Not that ugly like on Rushmore prototypes
The plot thickens, that's nothing like the other pictures. In the others there's a nice hard radiused guide that sends the cable down the bars, this goes into the fairing like pre-rushmore and doesn't look nearly as clean.

now that I've taken a closer look at it, you appear to be onto something, that does not look like a cable at all, it looks more like a hydraulic line, except for where it enters the lever, but there is no reservoir.......? Has anyone confirmed that it is definitely a cable system? has it been announced by the MOCO?

Hard to tell from the pics. It appears to be the same cable adjustment cover that is used on the M8 Softails, but it runs along the right down tube, instead of the Softail's left.
