Good news, 4K Blu-ray fans: Dolby confirms that Dolby Vision 2 HDR can work on existing players and disc tech — bad news: it's up to the manufacturers, and Sony already said 'we do not plan to provide an update'

• Dolby confirms that Dolby Vision 2 HDR can come to existing 4K Blu-ray hardware, including both discs and players
• However, it will require the player manufacturers to work with Dolby on updates, and Sony says it has no plans to update, with no comment from Panasonic or Magnetar
• Dolby says that Dolby Vision 2 TVs will still show visual improvements with Dolby Vision 1 discs, because of the upgraded processing engine

Dolby Vision 2, the next generation of Dolby's HDR format, is rolling out to its first TVs right now — and Dolby answered one my most burning questions about the new tech, which is whether it can come to 4K Blu-ray as well as streaming.
