I have to say I don't know much of the features that ARM version will have that I won't be able to have on my older generation Wooting two HE, but I know I could be interested of of just buying the PCB (with the "chips" mounted of course) and then just replace the one I already have.
Would it be possible to have a "update" round for people interested?

you can theoretically request just a pcb but you will basically almost pay the same as the full keyboard since youd basically replace the actually most expensive part about it
and if you want to know the features the arm one has its basically just a bit more stable scanning and a ton more space for profile stuff
