Our proposal to Cryptopia will require us to do a wallet upgrade.  We are not going to start that effort until Cryptopia agrees and confirms what we are offering will work and they can support it.  We can do our work in about a week.  After that, it is up to Cryptopia to do work on their end - I have no idea how long they will take.  They would like to get it out of Maintenance Mode as would we.  They have LOTS of coins in Maintenance Mode that make zero money for them, so the sooner that changes, the sooner everyone can trade and make money again.
