The real confounding issue with our own Milky Way Galaxy's black hole is that to see it we have to look through a lot of dust. So my bet is we will see an image that is much more detailed than before, blurred a bit by dust.
A real good video on what this particular Black Hole might look like was made in 2019 by the very good channel Veritasium.
Likely Media And General Public Reactions
As for the general public and general media we can hope that they learned a lesson and will not try to make the story interesting by trying to focus down on a person. BIG collaborations like this are team efforts through and through. No one can do this alone. Even the people who first conceive of these efforts are not really more important than those who bring it to fruition. Very little in science has really truly been done by a lone genius.
As for us scientist. Well anything they show us will be great. As a gravitational wave physicist I'd say that what we do teaches us about not just close to the horizon but about the horizon itself. That said at best we produce squiggly lines that make more sense to turn into sound than an image.
It would be interesting though to be able to have EHT monitor an in spiral while we observe gravitational waves from the same in spiral. Maybe someday.
