I should have taken some photos at the shimano tour I attended yesterday, but without specifics I can say it’s an entirely new cable pull and entirely new cog pitch. Every speed of cassette is essentially an 11sp, with spacers on the back side to eliminate cogs on the 10 & 9 speed. There are speed specific shifters, derailleurs, and cranks, but a lot of cross compatibility with blocking shifts using limit screws and such. It’s a bit of an upheaval with another new standard, but paints a promising future in the service world.

They’ve clarified it’s a different pitch since the XT 8130 release, and Andrew Major at NSMB tried to use the 8130 cassette on a regular 11 speed bike and it shifting ok on the stand but not so good on the road. So that’s well and understood.
But it might just be 10 speed spacing anyway, and Shimano could be stretching things a little when the incompatibility only exists for 11 and 9 speed version, much like Microshift swore up and down Advent X was on its own special pull.
The Reddit poster measured 3.7 cog spacing and 3.5 pull which would give you a ratio of 1.05 which is darn close to Dynasys 1.1ish. If you trust those numbers it at least shows they didn’t split the difference between road and mountain and shoot for 1.3.
Unfortunately a lot of the posted numbers, like the old Art’s Cycles blog post about pull ratios, are riddled with errors, so it’s tough so far to say what really works.

They had a few slides with charts comparing the exact numbers, and while it was quite close to one historical version, I believe dyna-sys, it wasn’t exact. Real world use I suppose you may be able to fudge it.

we’re putting the shitty shiny rainbow look on good bike parts now?
Bro it’s called oil slick and it adds $100

Self-extracting bolt? I don’t see any threads on the crank arm for a puller.

When will nice silver campenaerts come back? Black XT wet dicks aren’t gonna vibe with my silver 8 speed era XT everything else.
From big 3?
Never

Look at some campy interviews and they’re like “we’re only interested in making new stuff”

If you don’t care about staying with XT, the Alfine S700 brakes are silver and wallet fire XTR brakes are silverish.
But otherwise probably never outside of special edition stuff.

reportedly the new Force AXS chainrings are the same thing as the Red AXS ones, minus the polished finish.
$80 more for that polished outer face. I don’t think high-polish groups are coming back any time soon

Head is spinning a bit as a card-carrying mechanical Shimano dork who hates dead ends. I’ll say that my XTR12sp shifter is super clicky, and the feedback doesn’t make me loyal to HG+. The GRX shifter is good, but not so good that I’d hesitate to swap it out should LG etc win the mechanical arms race. I’d give up some weight savings for availability in lbs…which usually follows from which groups are strong in the OEM game.

The future of mech is former sram Chinese factories and Microshift
If campy makes a chorus eps it’s game over for any non mech over 11sp

Some of this feels very XKCD 927, I appreciate the trickle down and interchangeable shakes and flatties is cool and OK durability for commuters and all that, but do I really want a 1/2 pound heavier cassette so I can use my $30 11 speed shifters with a 9 speed cassette? Like if you can cram this pull into a cheapo shake, why didn’t you just put GRX on Dynasys to start out with? Regular 11 speed stuff isn’t going to go away because SRAM and everyone else.
