Indeed, but BSI remains the latest and the greatest, so it is just saying best in class sensor tech.
It is hard to be better than best in class but I agree anyway that the success of this systen will not be driven by a few % in sensor image quality. Usability, AF performance, EVF experience, ability to use existing lenses, lenses quality and roadmap,... will be more important.
Had they not mentionned it they may have been another FUD campaign such as the one that preceeded the D850 release when internet experts here and elsewhere were claiming with 200% certainty that the D850 sensor was going to be mediocre at best. :;
