We really cannot tell when would the management do it. If I am not mistaken late 2016 they have been doing beta testing for the new forum. People were giving feedbacks and keep on asking the mods when would theymos release it. Most of the establish member were also saying that it might be released on the mid or late quarter of 2017 but it doesn't happen. In the end it still boils down to the management decisions.
All we can do right now is to wait for the further notice and be patience
