So back to no concrete timeline at all

My previous point is still a sense of wonder at ED being reviewed to such an extent on a product that's not available to consumers. OR needs just 1 supply-chain hiccup for the 18-20 month estimate to turn out seeming remarkably astute.
Towards the end of last year -
"
Mitchell says the consumer version, which is "months not years away," will run "at least 1080p.""
- which at its best meant for christmas last year, at its worst christmas this year.
I think, like Elite and Star Citizen only with hardware to contend with as well as software, all these Kickstarter projects are in the public's view for far longer than products normally are. So it seems like they're taking forever but really, they're just in a normal development cycles which includes not really knowing when they'll be finished until that time actually gets very close. It sounds like they're "wrapping up" Dev Kit 2 which is a feature complete version for developers... that sounds like it is indeed getting very close if they're creating that for devs to get their games tweaked for the consumer release.
Also, the OR Dev Kit has been available to consumers from the start - via the Kickstarter and then on their web site. You didn't have to be a dev to get one, I certainly wasn't, I just backed it because I wanted one to play with.
Your sense of wonder is matched by
most people's experience of actually using one, and more relevant here, those who have used (and are using) one for ED. You probably have to try it before you can truly get why they're so excited about it.
