I hope they're retaining the 4:3 aspect ratio. Samsung IMO shot themselves in the foot by switching back to 16:10 for their recent tablets after going with 4:3 for the Tab S3.<p>16:10 on portrait is far too tall and narrow to use comfortably, while in landscape it's far too wide. 4:3 has a nice balance, and is shaped like a piece of paper, which is extremely useful when reading PDFs. Websites also render in their desktop view in portrait, whereas you get a weird semi-mobile view in 16:10 on portrait due to the breakpoints that have been set on most sites' CSS.
