The future!
Maybe.
All seems reasonable but as there’s plenty of scope there for ‘new standards’ and potential for Shimano to decide to do something differently leading to *more* new standards...
<grabs popcorn>
Haven't we already done axle-mounted rear mechs?
They do solve an accuracy problem but also remove the fusible link of the hanger. Doing that on an expensive electronic derailleur especially seems questionable, but as the article says, none of this may happen or odd features may make it into new designs- this is kinda SRAM’s wish list of what they’d love to do rather than a manifesto...
Shimano Hone, never really caught on. Probably because different frames have different rear ends and no one wanting to adopt new standard.

SRAM + hydro = a solid 'no' from me.

"Ok lads, we need to up the cashflow. Let's make the derailleur even more of a consumable than it already is."
The future is mid mounted gearing.

Everyone seems to be inventing one every five minutes
The future is mid mounted gearing.
But only once they've sussed decent non gripshift shifting.

Yeah, on that note why is it that every single gearbox/geared hub mfr has a think then decides "**** it, let's use gripshift"?

“* it, - that's basically what I think every time I change gear on my Rohloff.
When I first got it 15 years ago, that and the coffee grinder feeling in some gears was enough for me to ditch the whole thing and continue with singlespeed.
Now I'm getting old and frail, so the the Rohloff is out of the attic and back on a bike. I've used it enough now for the coffee grinding to cease, but that ******* gripshift feels like something that belongs with the cheap derailleurs on a BSO, not with a precision hub like the Rohloff.
Electronic gear shifting is the obvious solution.

Very much this, I can't for the life of me figure out why Rohloff, Pinion etc haven't already got electronic shifting, wireless even. It seems such an obvious solution to the problem that I am sure I must be missing some obvious reason why it hasn't been done yet.

My XT clutch mech has been made really nice and easy to service and repair. They didn't have to do that, but did. I don't think Shimano are guilty of this.
Re the mech - didn't they just move the mech rearwards to account for big cassettes? If that mech is under the axle it'll need to be really low down with a 50T sprocket under it. I like the hydro shifting idea but hasn't it already been done?
I think gearboxes/hubs have a gripshift because you need to move a lot of cable and there's more resistance to it - so having less mechanical advantage would make the shifter too hard to push - gripshift solve that problem, and also on the Rohloff it means it can pull both ways. I agree that an electric system for that would be ideal.

I think the idea is that the parallelogram part of the mech sits horizontally to prevent impact induced 'ghost shifting' whereby the bike hitting big rocks or roots causes the mech to bounce which causes the momentary shift as when the mech moves down with the impact it also moves across. Making the parallel plates of the mech horizontal stops that from happening. It also loks like they have increased the offset of the guide jockey wheel to compensate for the further forward position and re-alignment of the mech. So it shouldn't be any lower hanging than the current stuff, possibly even less since the mech doesn't move down as it moves to the larger end of the cassette.
The hydro stuff isn't to do with shifting it's to replace the friction clutch, the idea being that it works like a fork damper with heavy, high speed damping to prevent the cage rattling forward over the gnar, while having little to no low speed damping so that shifting is as light as without a clutch at all, the return damping is also little to none so that the cage snaps back to keep the chain tension.
Would I need to hacksaw my derailleur hanger off of my new frame to fit that mech?

Rohloff have but currently it only seems to be for hubs on ebikes. There are few options out there for shifting the Rohloff with triggers or even with modified SRAM levers for drop bars. None of they cheap enough for me to consider but If Rohloff make electronic shifting available for existing hubs I might be tempted

The future is 9 speed. 🙂
<span style="font-size: 0.8rem;">Well, for long as they still make it.</span>
I didn't even edit that, just altered it a bit before posting FFS.
Singletrack - get yer hedge cut before it's too late.

Patent implication is that you would need a whole new frame.!! Not likely to be retrofittable to anything. Depending on how they did the bolt thru connection it would need a different frame/dropout, a specific (possibly new) thruaxle standard (the patent also mentions 15mm axles several times so....), possibly a new hub standard, as well as the derailleur itself.
Yeah, on that note why is it that every single gearbox/geared hub mfr has a think then decides “**** it, let’s use gripshift”?
I'm reliably informed that a trigger solution for gearboxes is being worked on and tested, which I'm looking forward to!
Shimano do a cable trigger shifter for alfine/nexus 8 speed hubs, as well as Di2 alfine
