Cito del sitio web de Eureka, donde se especifica que habrá tres ediciones distintas:
DVD, Blu-ray, and limited edition Dual Format (DVD + Blu-ray) SteelBook
Qué extras traerá cada una, no lo sé. Estos son los que figuran:
o 150-minute reconstructed and restored 2010 version (including 25 minutes of footage previously thought lost to the world)
o Lavishly packaged editions with wraparound embossed sleeve, and a limited edition SteelBook
o Pristine new HD transfer (1080p on Blu-ray)
o New 2010 symphony orchestra studio recording of the original Gottfried Huppertz score in 5.1
o Newly translated optional English subtitles as well as the original German intertitles
