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.

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.
