I have large doubts that they gonna make the complete deal. The numbers so far are not that impressive: 5000 people have taken the 5000 first 600$ deal (5041 actually?). That was not surprising that there is a certain rush for it (and that was a one-day deal) and that makes already 3 millions, so almost everything they have collected.
5000 people out of the Ubuntu/Linux community, not that great, just normal I would say. The first 3 million is to show exactly what is happening: a nice start.
Now comes the true challenge: 830$ deal and only 161 people! Let's see in next days (clearly the first day was all about the 600$ deal) but I am not sure that so many people are inclined to pay the full price one year in advance. I prefer the pre-order thing with 100€ in advance that Jolla has proposed.
But even the 20$ support is only done by 900 people so far... And you need quite a large number to get 30 million with 20$ support...

I hope they gonna make it because that would benefit Jolla as well: some of the open source is shared between them. They found a niche: high level segment, but that means that they target probably more the US and then Europe. Is it enough to attract enough people, not sure about it?
They want to be innovative in the hardware and the software, that is good but much more challenging (like a new technology in battery, ok nice to hear but sure about having the people and the partners for that?). A lot of promises but even if truly they are open: you can see number of people signing for the ubuntuedge, you have specifications,... but then one-year in advance, a lot can happen and then people could become mad if some of the deal is changed...
Because they conclude with "specifications are subject to changes " ...

I'll wait till the end of the campaign to see if I participate with the 20$ deal. I do not want to encourage them too much in the first days [considering that I have chosen Jolla and will not buy both phones]
