I reached out to a person in MarComm that was listed in the Press section of Toyota's website. She confirmed that the press release was incorrect and was meant for the '20 Sienna.I think they made a mistake with the model year. The nightshade edition was available in the 2020 model year.
Edit: Here's the Toyota press release announcing the nightshade edition being added to the 2020 Sienna.
The Toyota Sienna, still the only family van in the segment offering available all-wheel drive, enters the 2020 model year looking as slick as ever thanks to the newly offered Nightshade Edition for all FWD and AWD Sienna models.pressroom.toyota.com
