I’m not (yet) placing much on those pics (same as early designs). Note, that the stereoplug seems to be on the opposite side to the three switches in that (sides seem mirrored - other has volume or some other rocker type switch and smallet button). And no visible holes for cards.
Looking at the older day 16 “red overlay” pic, I agree with the front camera placement. Notice in that how the rectangles (kinda Tetris-block L-shapes) are positioned over the M.2s…
