According to the
new Armory roadmap, the major pre-requisites for the current existing hardware wallets would be dealt with as the 2nd priority on that list (BIP32 aka HD wallet format). So there could easily be progress up to that point as early as the summer, it depends somewhat on how much sophistication goatpig intends to put into the design of the new format. It's possible that actual implementation of the hardware wallet could come as late as stage 4 (the haggling and horsetrading stage
). But it also might only be 3 hours of work once the BIP32 wallet design is complete. goatpig may eventually tell us more.
