Question: When will the fourth season of The Killing be released on Blu-ray and/or DVD?
Answer: The entire fourth season of The Killing is set to premiere exclusively on Netflix starting August 1, 2014. Both Netflix and Fox Television Studios (the production company for The Killing) hasn't mentioned if that season will be released on Blu-ray and/or DVD.
Because a majority of Netflix's exclusive content was eventually released on Blu-ray and/or DVD, I can provide a potential release date using that data:
Series - Season
|Premiered on Netflix||Released on Blu-ray and/or DVD||Days Exclusive to Netflix|
|House of Cards - Season 1||February 1, 2013||June 11, 2013||130|
|Lilyhammer - Season 1||January 25, 2012||December 3, 2013||677|
|Orange is the New Black - Season 1||July 11, 2013||May 13, 2014||306|
Using the data above, I've come to a conclusion that the fourth season of The Killing could potentially be released on Blu-ray and/or DVD as early as December 9, 2014, although a June 3, 2015 release date is more likely.
