The best guess is February-April time period.

It is going to depend upon how things go with the testnet and what issues arise. The expectation is to run the testnet for 90 days which would put us at the middle of January. We will see if that has to be extended and how long after that it will go live.

I would expect a minimum of 30-45 days after the testnet is totally complete before the hard fork does occur.
