It's the norm in commercial aviation for prices to vary according to order size and timing, delivery slots and whether the buyer is an airline or a leasing company
(i.e. Boeing publishes a "sticker price" but its customers don't actually pay it)
In this case, you've got the added complication the aircraft is still a work in progress, and so what's actually negotiated is likely to depend heavily on timing of payments and cancellation clauses.
I am curious about whether the pricing ballpark is in the "new turboprop" or the "operating economics make it cost-effective to replace ancient piston operated aircraft in a relatively short timescale" range though. That could be a big deal for some low-use routes and in markets like Indonesia and the Philippines.
It's not even close to the same market. This thing seats 12. A cat ferry can seat more than a thousand people and a couple of hundred cars on top of that.
You probably want the comparison to a helicopter - because that's the same market: Can take off directly from the city, skips TSA security, seats 12.
Operating cost is about half that of an aircraft though. 100% battery electric propulsion system!
