I'm sure the uncut DVD will have longer segments with all the side characters
and if I'm hearing things right they're including animated(?) Tales of the Black Freighter bits, with the option to have it all interleaved into the movie at the proper points. if this is old news, hey, but I was pretty excited when I heard it so there. it wouldn't fit quite as well without the sort of nautical theme the original ending had, but hey.
all told, it's going to be an incredibly long watch if they include all the stuff they should (I particularly missed the Hollis Mason thing and Rorschach's Kitty Genovese story and the way that fit in with the original grouping of secondary characters right before the end,) but it's probably that or make it into a miniseries (which probably would have been much better in terms of content and pacing but wouldn't have been nearly as profitable.)
it just so happens that the last movie I watched was watchmen so just read this post from the top again and we'll call it done.

Says Zack Snyder himself, "The überfans of this property are going to go crazy for that."
aww yeah
