I have been waiting for this coin to come out for what seems like ages but recently I heard a rumour that since the developers are all well known, they might be scared off by the US govt. Obviously the powers that be would not want something like this coming out.
Same goes for Dark Wallet - I heard their web site was taken down for a while due to their involvement with encryption and privacy. It's back now but don't forget what happened to Lavabit and Truecrypt. There are forces actively working against anything involving encryption and privacy.
I do hope we hear more about what's going on with Zerocash soon!
