Interesting review, as they come to the same conclusion the video review of "The Camerastore", which we had a talk about the other day ..
That is, that the sensor is equal to the sensor of a Nikon D5500 in therms of noise and that you have to compare them at a full stop difference, as Fujis ISO200 equals Nikons ISO100.
Fuji X-Pro1 @ ISO200 compared to Nikon D5500 @ ISO 100 - equal shutter speeds, here is what they say:
"It's widely assumed that Fujifilm's X-Trans sensors use low-noise Sony silicon behind their unusual color filter arrays, and the performance of the X-Pro2 is certainly up to that standard. Compared here with the Nikon D5500 (using the same shutter speeds so that they are working with the same amount of light), you can see very similar amounts of noise up to a 4EV push, and possibly a fraction more after a 5 stop push, though the difference may simply be one of grain structure, caused by the different demosaicing processes."

So the X-Pro2 has no "magical" X-trans sensor, but one of the best APS-C sensors. Regarding the X-Trans array, I fail to see a "better" noise structure in the RAW files than a conventional sensor, but there seem to be some benefitts regarding moire.
That said, I very happy with my X-Pro1 and it´s noise performance, but I would love it just as much with a conventional sensor I guess.
