"As we reported on our previous post, a full 36 percent of disc sales of Warner's 'Watchmen' have been on Blu-ray. This is a record-breaking figure, even for action movies. For example, back in September 2008, 'Iron Man' got "only" 17% of its sales from Blu-ray. The previous BD percentage record was for 'Quantum of Solace', released March 24, 2009, which got 28%.
This feat is all the more remarkable if we consider that the DVD had both one- and two-disc editions, and that an Ultimate Collector's Edition Blu- ray has been announced for later this year."
