Hard to say. The github hasn't been updated in several months but the other developers of armory have been active on this forum recently.

I used Armory in the first place for cold storage. Switched to Trezor and no longer use it. Now that hardware wallets are common and inexpensive Armory is looking long in the tooth. If it would fully support Trezor (multiple hidden wallets with passphrases) it would have an edge over myTrezor and Multibit HD as a more private solution. I would very much like to use a fully validating node with Trezor. Would I pay for it? Nope.
