A pair of images, obtained by @IceUniverse show what the Galaxy Note20 will look like. The images seem to be schematics for a case design (which explains the huge bezels) and show a device with a centered punch-hole camera in the display and a triple camera on the rear.
The squareish corners are reminiscent of the Galaxy Note10 series.

This is a very early and unconfirmed first look and it could end up being off the mark. But it does come from a credible source so it's likely at least mostly accurate.
The Galaxy Note20+ will come with a 4,500mAh battery and 108MP camera, while the Galaxy Note20 will have a 4,000mAh battery and likely a 12MP main camera, as on the Galaxy S20/S20+. Rumors of a Galaxy Note20 Ultra have repeatedly been rebuffed.
Both the Note20 and Note20+ will come in August.
