What game industry and preorders have taught us — never do any preorders until the real thing is out and first reviews start coming in.
But when we were finally given a hard date, it showed up on that date, and we've been happy with it since. The only reason I don't jump in line for the ID is because my wife and I are really hoping they build that concept van to replace the '81 VW Westfalia we've got now. They announce that for pre-order, and it's "shut and take my money" time.

A car you can at least get a bit sooner by taking the gamble of preordering.
