I see, but I have been here since a long time, and I don't think the discount ends soon. After all, it should have ended months ago.
(Just talking about the pro1, no idea about the astro). But you are of course right, it is a bit of a risk, you could use the discount if you wait.
But just do not forget it is a crowdfunding platform. So it isn't guaranteed that you receive anything. I do not believe that anyone will loose the money, but it is still important to know the risk.
