One of the ETC developers answered for the question on Reddit that the Emerald wallet will be finally launched next week:
Ethereum Classic will be probably used now for ICO's as a cheaper version of Ethereum. Current ETC price is not even a 10% of ETH so there is a lot of space for grows. This is great news that will start pushing ETC price to the moon. In January 2017 Ethereum price was around 10$ it is 2 times lower than current ETC price that means if a lot of ICO's will be launched on this crypto it has chances for thousands % raises in a year!
