Hey Chris, there already is a Alpha Firmware with OpenPGP and OTP available and we are working on it to bring these features to the stable firmware, but this will for sure take some more time (talking about a "months" ballpark here) - we have clearly underestimated the efforts to fully stabilize these features, but we are trying hard to progress and will keep you updated on the progress as good and transparent as possible. Overall we see the Nitrokey 3 as a platform and we do not see any successor anytime soon, we even expect it to be available far longer than our last generation Nitrokeys (e.g., the Pro is now available for more than 5 years).
