I very much doubt cryptsy will ever relist it the way things stand right now.

However, cryptsy's fork excuse is complete and utter rubbish, the real reason is that it was at the bottom of the XPM market with no real potential for movement due to the high coin supply and massive walls.

Another reason is because the stake difficulty is currently very high which is something cryptsy has contributed to by limiting outgoing withdrawals to 99m meaning that their customers probably have many more transactions in their wallet than they need to. (Lots of people trying to stake constantly keeps the difficulty up).

Because the stake difficulty is high it makes it hard for anyone to run a wallet with more than a couple of hundred transactions of stake age unless the wallet is encrypted and locked. An exchange will have a bigger problem because they likely have many thousands of transactions so the only way they could maintain a functional wallet at the moment would be to purposely destroy coin age by moving coins around the network, resetting the coin age.

I think the only hope for it returning to cryptsy would be for a complete relaunch of the coin with the currently minted coins being divided by some value* and premined in the first few blocks, the coins in the new version could then be claimed by the current owners in the same way that has been done in other coin relaunches such as ADTv2 which cryptsy has just announced they have switched to in their latest tweet.

* Perhaps introduce decimals and divide by 1 million, this would bring the total down to 43 million instead of 43 trillion and shouldn't cause an issue for even smaller holders getting their new coins.
