All roadmaps are tentative and simply best estimates, especially around sensitive financial software. We’ve made many improvements to the system since posting that roadmap (w.r.t., performance, security, and usability), and we are not going to launch any system until (1) it has a user experience that meets our high standards (2) it has passed an extremely rigorous security review (some of the best firms in the world), which is ongoing. We will launch when when both of these criteria are met.
Whatever the date: when we release, we aim to blow people’s expectations out of the water. Keep in mind that what we are doing is a new thing: no one has yet come up with a way to make decentralized interfaces accessible to non-experts and to allow normal users to benefit from these kinds of advances in trust, much less to combine them with the kind of performance we are envisioning. This stuff is easy to get wrong, and it is important to us that we don’t cut any corners.
