I don't think they will make it. A fancy demo won't satisfy backers. Last years demo is nowhere to be found. A brilliant demo will make backers angry. Why waste time and money on another demo when 3.0 is still MIA. No matter how Chris will talk about his visions, his dreams, his plans and all the difficulties when doing things nobody has done before, backers want more. They want something they can actually play with. Doesn't matter how crappy (to some extend) but give us something. There will come a point when they demand that whatever is ready will be released and they will comment and report on the bugs. And that is when Chris has to admit that there just isn't anything there to be released or he has to release the crap he does have and that will be much, much, much worse than any backer could ever have imagined.
Chris is fucked, no matter how you look at it. Unless he has lots of money left, which he doesn't. It wouldn't surprise me if 2017 is the last year of CIG...
