Looks like the 1.6c buyer from last friday has moved down to 1.1c, and now a couple of sellers have appeared.
Either way, I expect a continued move upwards. It was raining pretty heavily all weekend in the trial sites so hopefully by now (or very shortly) the Burkina Faso site has enrolled all 50 people.
That would be announcement worthy and may come a lot sooner than what others think imo.
