Battlestar Galactica: Blood and Chrome will be released first in ten seven- to twelve-minute episodes on YouTube channel Machinima, beginning this Friday, according to Entertainment Weekly.  All ten episodes will be released over the next four weeks. 
A two hour version will air on Syfy in early 2013.  The third tier of the release will be an unrated version released in Blu-ray, DVD, VOD, PPV, and DTO, according to Variety.
Originally planned as a series, the pilot apparently underwhelmed, because a series order was declined last spring (see "No 'BSG' Series on Syfy").
