Will the SL3 have a global shutter?

Going with the "sunny 16" rule, and the min ISO of 250 for this camera, we get an exposure of 1/250 at f:16 in full daylight. That's 1/1000 at f:8, or 1/32000 at f:1.4. Sony's fastest lens is a 1.2, so let's call that 1/40,000 at 1.2.

There are two ways to get to 1/80,000: you can bump the camera's ISO to 500 or above (which will provide much-needed head room in the highlights), or you can shoot near the equator where "sunny 16" becomes "sunny 22" on a clear day around noon. I guess you could also use it if you wanted your flash to overpower daylight in similar conditions, for aesthetic reasons.

The SL2 (and many other high-end cameras) can already do 1/40,000 with electronic shutter, with a wider ISO range, so your main use case will be wide-open daylight fill-flash mid-day near the equator with a 1.2 lens, when you've misplaced your ND filter (but not your powerful flash).

That's not nothing, but it also isn't much. My Leica III has a top speed of 1/500, and it hasn't bit me yet.

Of course, I'm not a professional sports photographer; few people are. Is this enough of an innovation to get a few high-end pros to switch from Canon and Nikon?

I think the point it not to reach 1/80000s. 

Think about a shoot outdoors at any time of the day and you want to shoot portraits with 1.4f and use a studio light. 
Until now it was possible with ND and HSS, which are not giving enough power to use a softbox or other soft modifier.
The only other way was with a central shutter to limit to 1/1000, but you won't be using the full range of lenses available for 35mm cameras.

You are right of course. I looked for situations where a 1/80,000 global shutter allowed you to take shots that were previously impossible. There are situation where a global shutter makes things easier.

How much easier is open to interpretation. ND filters are very common, you still need to use powerful flashes, and it's likely that you will need more flash fill (aka: a lower lighting ratio) because of DR limitations associated with global shutter.

It isn't a game-changer for me, but it could be for others if it solves problems that they encounter on a regular basis. Obviously, the catch is that it shouldn't create other problems which were previously solved (like lower ISO and higher DR).

The other question that I think I answered is "how much light do you need in order to use 1/80,000 with this camera?" The answer is mid-day equatorial sunshine with Sony's fastest lens. There are other use case, of course, like shooting straight into the Sun without any filter.

As a very long time Leica user (my first camera I bought was a Leica CL and this was not the recently abandoned one) I migrated to Hasselblad. As I used many different camera systems I appreciate HB's UI but second comes Leica and I would be interested I a second camera but it needs good macro capabilities. At least now there are 2 macro lenses for the L-system:  the Sigma 105 and the just announced Panasonic 100mm/2.8 which is an amazingly small and light macro lens in that focal range. One main issue for me getting a Leica SL is the lack of built in focus bracketing (only Panasonic S has it within the L-system). So I am hoping that will be implemented in the SL3 but I am pessimistic. I still think back to the Apo Elmarit 100mm/2.8 macro, their best lens I had after the original Summilux M  75mm. I don't understand why Leica is now completely ignoring any more specialized photography (that is including tele which was one of their obsessions decades ago).

There’s more. Sigma has a 70mm too. And Laowa has a few options in native L mount.
