How much better, I don't know, but I suspect it might be substantial in bad conditions (very rough surface and rapid maneuvering).

I have to disagree with you on these last points of yours.
Three points of support for a *static* system is obviously the most stable. But in the case of the *dynamic* system of a three-wheeled transporter, there will be many lateral forces pushing the device over onto only two of the three wheels. If the rear wheel is used for steering, what happens to control when it gets pushed up into the air? Or what happens to steering control if one of the other wheels gets pushed up?
No, I'd say Segway wouldn't want to throw out the baby with the bath water and all of a sudden not incorporate its magical dynamic balancing system with at 3-wheeled transporter--in a similar way to the way it was kept with the Centaur. That's why I'm guessing that a third wheel would answer the need for greater stability for when the machine was traveling very slowly or stopped, in which case, it should "caster" and follow along with its two big brothers which have been doing all the Segway-style heavy lifting of propulsion and steering.
