By that do you mean "closer to a year before Tesla delivers a base Model 3"?
I am factoring in that, since Tesla and SpaceX employees were give the opportunity to make the first reservations, and since many of those employees may only be able to afford the $35K base version, Tesla will therefore be producing and delivering the base version once production commences. To make those employees who reserved and want the base version or something very close to it wait up to a year for their car after production starts seems unreasonable.
We know that with the S and the X, Tesla first offered only heavily optioned versions, primarily (I believe) because that resulted in more revenue, money which Tesla needed to expand operations. And those were cars that few of their employees could afford. Certainly Tesla still wants to maximize revenue and continue to expand, but with about 400,000 $1K deposits that's a lot of revenue right there. With the Model 3 Tesla has made a point of allowing their employees to make the first reservations. Those employees deserve to get their Model 3 early and configured the way they want.
