Looks interesting, and is supposed to clear 60-584 tyres.

I'm not a huge fan of the Midnight Special - why does Surly insist on coming up with their own weirdo dropouts? And the straight-44mm headtube is my least-favorite aesthetic feature on modern steel frames. I know they need a bigger head tube to allow for carbon forks with tapered steerers, but tapered head tubes look so much better than giant straight ones...

Very interesting.
The Surly is possibly the first mass market 650b specific mid-trail
bike! 56mm with a 16mm flop.That's the same as my Stanyan conversion
with 650bx38 and I like it a lot.
Not sure why the BB is so high though. Designed around 47mm tires they
could have easily gone with a 70 mm drop.
The All-City is a more common 65mm trail, 20mm flop bike. Much more
gravel oriented.
On the other hand I really like the aesthetics of the All-City. Could be
the new touring bike I STILL haven't bought? Procrastination For The Win!
Tapered head tubes are complicated too, both to machine and to understand which headsets fit. I'm not convinced tapered gives any more options eithet, for instance I think Anglesets fit 44mm head tubes but maybe not tapered. Anyway, I almost suffered brain damage trying to work out what headsets might fit a tapered head tube with a tapered and/or a straight fork. 44mm is way simpler. And cheaper. And it matches the tyres. ;-)Later,Stephen

David, Stephen: Yeah, I know that straight 44mm head tubes are significantly cheaper than tapered head tubes, and I'm sure that's why Surly (and many others) spec them. I still find them visually offensive when paired with comparatively skinny top and down tubes.
Sure. Normal 1-1/8" steerers generally take a 30mm lower crown race. Cane Creek sells EC44/30, EC49/30, IS52/30, ZS44/30, ZS49/30, and ZS56/30 lower assemblies.
So let's take my Santa Cruz Chameleon: Uses an IS41/IS52 headset. With an IS41/28.6 upper and IS52/40 lower, I run a 1.5" taper suspension fork. If for some reason I wanted to run a fork with a straight steerer, I could swap the lower assembly for an IS52/30.

The through axle isn’t really TA. It is the worst of both worlds. See attached pics.
-Torque spec is 16 Nm, tough with a multi tool.
-dropout doesn’t surround axle so axle can move in dropout.
I find this design choice baffling.
Actually, in my experience most everyone who is interested in low
trail has that interest because they have had issues related
directly to flop. Plenty of it makes climbing at slow speed,
especially with a load on the front, really tricky because the
bike is so desperately unstable, seeking to dart off sideways of
its own volition.

I've had two bikes dart across the road at 90 degrees to the
direction of travel as a result of that wobbling instability. As
for "problems at more normal speeds with low trail" -- I've never
encountered anything even remotely like that. But, we've had this
conversation before. And I'm still mystified. To me there's
nothing more natural than the handling of my low trail bikes. No
shimmy, no trouble at all following a chosen line. I don't
paceline, but I do love to ride on what Jan calls "the fog line"
(we don't call it that here, perhaps because we don't have very
much fog, certainly nothing like what they have in the Pacific
Northwest).
Who even thinks about flop - unless it's to do with crappy films? The real issue IMHO is stability from trail - plenty of it makes holding a line on dodgy surfaces much easier mentally.
What is a "flop cliff"?

I don’t think the discussion is weird - though it is a bit off topic. My experience with low vs high trail fat tire machines is identical to Steven P’s. Low trail bikes climb straight at low speeds. High flop machines do just that - flop around. Which is why I am interested in the Surly MS. A mid trail design with steep HTAs at the larger sizes minimizes the flop common to high trail machines. Best of both worlds? A geometry to finally subdue Satanas’s obsession with trashing low trail (aka a mis-specced Soma POS GR?)
....And holy cow the MS is NOT medium trail. With a 50mm tire that machine needs to be size huge to get the trail down into the /50/s...

I very much doubt a steel bike running 650bx47 Horizons is going to handle like a road bike.
In a similar (but not too similar) vein, All-City released a drop bar 650b bike as well, dubbed the Gorilla Monsoon.https://www.bikerumor.com/2018/02/17/city-gorilla-monsoon-storms-27-5-drop-bar-monster-gravel-build/It's interesting to note how these two Quality brands carefully stagger their bike designs to avoid excessive overlap.
In particular, the GM has clearance for 2.4" tires whereas the MS has clearance for 47mm. GM has more stack and less reach for a given size along with a slacker headtube and more trail versus the MS. Both have similar mounts, but per each brand's identity, the GM is generally more ornate and prettier while the MS is more utilitarian looking. The GM would seem to be a great "gravel grinder" or a "monster cross" bike whereas the MS is totally an "all road bike." The former blends more MTB elements onto a dropbar platform whereas the latter is more of a road bike with more tire clearance.
Got a chance to look at the MS in person.
