Yes, indeed. It's been a long time. All outsiders can do is watch this thread for any updates. I think this 2019 is the best time to your version of a DAG network to see if it can compete with Obyte, IOTA, and Nano.
If you expect competition, you can be surprised. It will not be possible for very simple reason, Bitlattice is not comparable to those projects. They follow the right path, but still missing several crucial points. That's why we keep important details undisclosed.
As to the timing. If it would depend on technical issues only Bitlattice would be up and running since a year already. But then it would mix in and vanish among a wealth of other projects on the scene.
So, we decided to have a considerable backing first. This will provide us with means to extend the scope of BL. But the details we'll be able to provide no sooner than in May. The same applies to any reliable predictions of timing.
