Discotek Media responded to their release schedule post on Facebook. They have changed the release date for the Yoroiden Samurai Troopers TV series until April. Reasons for the delay are currently unknown.
It is still expected that the TV Series Collection will be the Japanese version of the series only. (Obviously with English subtitles.) There is no further word on any progress with Discotek Media acquiring the license for the Ronin Warriors dub.
