I think pre ordering won't die but people also won't do it if:
it's a new company with no proof of manufacturing ability.
the numbers aren't limited
you have to pay in full.
Company is not financially sound
I just preordered a $65,000 car with a check for $500 that's refundable. I cringe every time I see people handing over huge checks years early for a pin. That money could be invested wiser. I also think the fear of not getting will subside because so many pins are coming out and I've never seen a case where a pin hasn't become available unless we are talking King Kong / King Pin kind of rare.
