Cherry ML confirmed, it seems.
so let's see what's there.
Could not see a cable, although it might be visible in that perspective. So bluetooth option not ruled out yet ;-)
Mechanical function keys.
It seems that rubber keycaps are replaced by hard ones. Number, size and layout of functional keys seems the same.
Modified function keys allow switching between dvorac/qwerty (F3/F4), and pc/mac/win layout (F5, F6, F7). Seems to replace "=p" "=m" "=c".
Cannot read F8 key. May be something like "clear map".
F1 modifier gives a status, maybe something like "=s".
Any ideas for F1/F2 modifier?
So as hinted by natas206, same layout, rubber function keys replaced by mech switches with maintained layout, functional enhancements. For me, that is enough to wait for the new keyboard for buying.
However, I would have loved to have standard sized function keys (F1-F12) as a further row ontop of the number's row integrated into the key wells, maybe with the keys not fitting there (esc, print, scrlock, break, keypad, prog) added as further three-key-thumb-columns left and right the thumb blocks, respectively (where they seem to be sill easier accessible than in the present position). But I understand that this required a major overhaul including a fundamental redesign of the case, which might lead to considerabe increased production costs.
So let's see the device when it is finished.
