I am a new user to armory and I like it so far, have not had many problems,  had the database error once and was able to fix it but I have a lingering question as I do not fully understand all of the nuances behind how wallets and private keys work with armory and with the bitcoin core client.

Lets say I store my bitcoins in armory, on an offline computer and do not access them for 10 years.

If the bitcoin core changes drastically and armory development ceases to upkeep due to whatever reason will I be able to import my armory wallet to other alternative clients? And if so will a watch only wallet be able to be imported? or a wallet in which I have lost the passphrase and only have the armory paper wallet recovery?
