That was under the previous leadership when Stina Ehrensvärd was CEO.
Now they've taken VC money[1], and more recently merged with a listed SPAC[2] I suspect replacement devices will never happen because, you know, shareholders come first.
I wish Yubico had some serious competition, but sadly they don't. NitroHSM is not the same thing (plus has flashable firmware, which leads to potential security risks). Tilitis looks interesting, but its far from maturity.
