According to the rendered images revealed on Evan Blass's Twitter, the Motorola Razr 2023 will likely get the largest cover display of all its competitors for now. As you can see, the cover display takes out a huge portion of the back, even covering the area around the camera cutouts.
Another render also shows that the cover display will feature shortcuts to Weather, Calendar, Contacts, Music Player, and more as well as notifications icons and a battery indicator on the bottom left of the display.
The rendered images shown do not fully representative of the final product as it wasn't confirmed by Motorola. And there is no information about the specifications yet, so take this with a grain of salt.
