My dealer says no markup but who knows about that. To answer all of your questions, I want it as close to $40k as possible because that was the initial price point as stated by GM during the unveiling- and I am willing to wait. Whatever GM offers at that price point is what I'll take, so long as the nominal range is over 200 miles.
If Chevy welches on actually offering this price point, then sign me up for a $50k GMC Sierra Elevation. That truck has some of the niceties that are absent in the WT like alloy wheels, the midgate, and the iPad pro sized screen that I don't care about.
