Oh geez. In my opinion better not to announce release dates at all if they are in 2019. It's not what people want to see at this time and will crash the price of Steem.
What people (and the market) want to see is a release of SMT sometime in 2018. I would honestly consider retracting this post because of the impact it could have on the market and Steem price which already is floundering.
How about don't announce any launch dates or release dates until the year it's going to be released. If it's more than 6 months away and we are in a bear market it's a forever away.
