DVD, HD-DVD, Blu-ray release after a limited theatrical release. I don't know if that means worldwide or just the U.S., but I expect only the latter.

The Final Cut version (which will be shown in the theatres) will not have the Deckard voice-overs because that's something Ridley Scott was completely against. Basically Warner Brothers forced him to add that to the original theatrical release because they thought their audience would be too dumb to figure out the plot without the cheesy voice-over. The DVD release after the limited theatrical release this fall will include that version too, though. It will be accompanied by the 1992 Director's Cut (sans voice-over and dubbed ending) and the deleted scenes included on the Laser Disc version in '95 I believe.

Essentially The Final Cut version will be the Director's Cut (remastered sound and video) and some deleted scenes from subsequent versions.
