Multiple sources seem to confirm that the new documentary about moto racing called On Any Sunday : The Next Chapter, which extended trailer was one of the demos on the Atmos demo disc, has indeed been released with a Dolby Atmos track.
The Blu-ray is out today on Amazon and details are not included to confirm, but multiple sources are confirming the Atmos inclusion.
You can follow the link on the image to purchase from Amazon. I will let you know as soon as I can try the disc. Meanwhile, I updated the list of Atmos Blu-rays on the site.
