They were in #monero-dev asking questions yesterday so seems more likely that it's monero getting added:
At the bottom of this image Mullick states "Will get this up ASAP" so its definitely Monero
I have a feeling cryptsy are kicking themselves for not adding XMR sooner. Since Polo was the only exchange they have gained a lot of market share in the space. I can almost guarantee that ETH wouldn't have had 5000 BTC volume if Cryptsy added XMR earlier. The cryptsy team has let Polo gain too much market share and now they (maybe) have to try and make up for it
Serves them right. Hope they learn the lesson that Monero is a BFD
