The dev did not say he is waiting for the network to stabilize. He said coinexchange needs to update wallet. Coinexchange said they are waiting for dev to contact them. Someone is not telling the truth.
For everyone worried about the exchange, don't forget there has been a complete protocol change. I think the Dev's are making 100% sure everything runs on the new protocol, even yesterday I saw some old protocol show up on the MN list and then drop off. Once it's all smooth then Coinexchange will start up again. It won't be long. It's the investors slowing it down with old wallets, not the developers, they know what they're doing. There's some serious coding skill involved in coin architecture. It all has to be spot on to work for an exchange, or the whole chain goes out of alignment.
