Is ATLAS comet disintegrating?

Is ATLAS comet disintegrating?

New observations revealed an elongation of the nucleus and a lower magnitude

Is the probability to see a naked eye visible comet dashed? There were great expectations about this comet, and probably we can still have them. Although the last observations showed a longer elongation of the nucleus, indicating a probably its disintegration: this is based on the behavior of other comets in the past that got fainter after showing a nucleus elongation.

By the way, these are the news: after crossed the Mars' orbit and raised till a magnitude of 8.0, it has sunk till a 8.8 magnitude (remember: the bigger number, the fainter celestial body). Is this indicating about the comet disintegration? It's possible..but not certain.

The two astronomers Quanzhi He (University of Maryland) and Qicheng Zhang (Caltech) submitted:

We report the possible disintegration of comet C/2019 Y4 (ATLAS), revealed by the public monitoring program carried out by the 0.6-m Ningbo Education Xinjiang Telescope (NEXT). Images taken on UT 2020 April 5.6-5.9 showed an elongated pseudo-nucleus measuring about 3 arcsec in length and aligned with the axis of the tail, a morphology consistent with a sudden decline or cessation of dust production, as would be expected from a major disruption of the [comet’s] nucleus.

This seems meaning the "end" of the comet, but don't remember that comets are unpredictable. Let's hope ATLAS can realize what we expect for.
