Rough timeline for the first two milestones

I looked over the roadmap, is there a very rough timeline for milestone 1 and 2? are they planned for 2017? Q1/2/3/4 2018? Just a very rough idea would be interesting to get.

I got this estimate via slack: “milestone 1 should be achieved by end of the next quarter and for milestone 2 I think we are looking some time next year”
