By this time the developers should have already launch a beta site for us to view how the exchange marketplace should look like. We need to have a first hand experience on thier platform. We can also give some feedbacks that will help them for the additional development of thier platform.
I think they are on schedule with the timeline of their project. Beta development i think you can find them on the road map. I agree with you that it is better for us to experience how their platform will work and for us to give feedbacks for them to improve if there is any.
