Features on the Dawn of the Dead DVD?

According to the site, Dawn stars Ken Foree, Gaylen Ross, David Emge, and Scott Reiniger reunited for Anchor Bay to skip down memory lane...and we'll all get to hear what they had to say this Fall when the disc is released. Now, a lot of speculation is swirling around right now about how many discs this set will contain. We've heard two. Then three. Most recently we've heard four, that's from a reader who was in the presence of an Anchor Bay Dawn presentation held at a horror convention. The fourth disc will apparently contain Roy Frumkes' Document of the Dead. We've been unable to confirm that, however.
