I think the problem is that the Edge campaign flattened out so early. The link you provided seems to go flat at about the 50% funding mark. The Edge (appears to have) stalled at 20%. Unless it's just a transient bump, that seems far too soon.
I have no idea if it'll hit the mark, I just think the analysis doesn't hold water because it doesn't acknowledge the real dynamics of these types of campaigns.
This campaign could go so many different ways. The safest bet is that it won't succeed, simply because it is so groundbreakingly large. However, how many times have crowdfunding campaigns surprised you with their level of success? For me, the answer to that question is "tons of times". So I'm not taking a guess on whether it'll succeed. I'm just saying, "Good luck!".
