The biggest thing we can see from these renders are all the rumored Galaxy S23 colors, at least those for the base model. Those are from left to right Mystic Lilac, Cotton Flower (a gold/white colorway), Botanic Green and Phantom Black.
With a flat front and back and curved metal edges, the design is not that different from the Galaxy S22 series, aside from the new camera layout which uses individual lenses embedded in the phone's back glass, rather than a unified camera block containing them all.
Going by other renders and dummy models we've seen of these phones, the Galaxy S23 Plus should look exactly like the Galaxy S23, only with a larger 6.6-inch display instead of a 6.1-inch one.
The Galaxy S23 Ultra model, on the other hand, should be larger again at 6.8 inches, and have squared-off corners, curved display edges, an extra rear camera sensor and space for an S Pen stylus on the bottom edge to set it apart.
More Galaxy S23 upgrades leaked
Apparently we should expect a boost in speaker quality on the Galaxy S23 Ultra, particularly for bass tones. There will also apparently be an improved microphone for capturing sound.

For the Galaxy S23 Ultra's camera, a non-specific "focus problem" has been fixed. The anti-shake on the phone is also apparently very good, which should mean more stable images and video when recording on the S23 Ultra.
It's just under three weeks until Samsung's Galaxy Unpacked event on February 1, which is heavily implied to be the time and place where the Galaxy S23 series will be revealed.
We should see a nice collection of upgrades for all models in the form of new 12MP selfie cameras and faster Snapdragon 8 Gen 2 chipsets, plus new camera modes and faster RAM, if the rumors are to be believed.
