Rev 2 is functioning as expected on testnet.
Dan will keep releasing updates, and will let us know when it's ready for the mainnet.
We wouldn't want to risk your funds, so we will be exceedingly cautious about this. New and revolutionary technology means nothing to a person who loses his/her funds using it.
Nonetheless mainnet will be soon.
I understand that announcements can be perceived too radically, though it would be nice to know at least rough timeframe. The pessimistic one. Especially after everyone thought it was going to be ready for mainnet yesterday.
