It most likely will never make it to production. At this point in time, if the creators were being honest, they would either have announced an OEM sign up, or have announced that it has already been delayed beyond Spring 2019.
As much as I like donations to causes, donations to doomed causes who aren't honest about the probability they'll ever come close to a reality are useless.
They advertise lifetime updates for a product they don't even have a supply chain lined up? Really? And the money spent will serve to (according to them) support the development process? So who will actually pay for the phones ordered?
Wishful thinking is nice, but it is nothing beyond wishful.
