Fortunately for most (but not for us with original PCBs), the new controller and PCB won't be interchangeable with the original version. The real reason is because we are changing the connector pitch from .156 to .100. The previous PCB will work perfectly fine with everything else, but you will still need the legacy F xWhatsit if you are planning to reuse the original PCB.
EDIT: WCass beat me to it. Typing on the phone is brutal
The new PCB will have a slip-on (slot) style connector very similar to the beamsprings, and the new xWhatsit will be similar to beamspring xWhatsit (except the connector will be inverted so the controller sits behind the backplate as opposed to above). Both will have the connector pitch shrunk to .1
I plan on using my original PCBs like you (for multiple reasons). The only functional difference will be the winkeys and split spacebar are missing (no bigs). I do like the direct solder inverted approach I used with header pins. Really cleaned it up
