Sure, but I'd say they would wait to see the figures pre-order sales numbers before committing. They've got time until Doc is released in over a year or so.
Apparently sales of the original DeLorean were not huge and in line with HT order expectations, so they are probably waiting to measure the figure popularity and then make a decision yes/no on the car.
More collectors would probably be open to ordering a vehicle once they'd paid for their figures and have them in their grubby little hands. As opposed to everything all at once. Many would balk at ordering all at once, which equals less vehicle pre-orders.
But yeah, a real possibility it won't get made at all and a typical tease as you say.
Anyway, back to Book fo Boba. Are we there yet ?
