Probably true.
Notably, in these photos, there seems to be no visible hinges anywhere (left, right, bottom, top) to support a flippy screen. But the screen does seem a bit wider and deeper than the K-3 screen, and that new notch in the bottom centre of the LCD must fulfill some purpose. It could just be some room for the Pentax logo, or something more technical.
Interestingly, from the EXIF, these K-new/K-3 product photos were taken by a K-1 II on December 03, 2019. So about 9 months ago ... A lot could change between 2019 and a late 2020 release date.
