Por lo que he leído en el foro de Blu-ray.com, el director ha dicho que su versión será la que saldrá el 21 de julio en USA y que en Navidad añadirá lo del navío negro. Aparte parece que en tema de extras no habrán diferencias con respecto a los aparecidos en julio.

Sobre el ultimate cut:

Snyder: I don't know. There's this version that's coming out that's my cut and then the version that comes out at Christmas is basically "The Black Freighter" version which is probably a much-simpler giant movie release but without the walk-ons and everything. It'll be the only way to see that version of the movie. So if you're a fan of the complete experience, you'll have a chance to see it.

Sobre los extras:

Though WB confirmed that an "Ultimate Edition" will be hitting later (around Christmas), Snyder emphasized that the July edition's features won't be repeated and that the later release will be a more or less "movie-only" version, incorporating the "Black Freighter" footage back into the film. Though the later set's running time will be the longest version possible, Snyder's preferred cut will be the version hitting July 21st and that that version will contain the greatest special features. While the "Ultimate" version will not include the walk-ons, it will have an exclusive audio-only commentary.

Vamos, que vendrá la peli pelada con audiocomentarios y nada más.
