The British Board of Film Classification has rated Chocolate an 18 for "strong violence", and it "was passed with no cuts made". It was submitted by Showbox Media Group.
Update: Following that rating, Chocolate is listed at Amazon UK. The DVD will be released on November 3 -- the first definitive word of an English-friendly DVD of the film.
Meanwhile, Chocolate is coming to North America, screening in the Midnight Madness program at the Toronto International Film Festival and at Fantastic Fest in Austin, Texas. No word yet on a DVD release for the U.S. and Canada, though.
