Essentially, here's deal: When Network (which does all the production and remastering on the BDs under license with ITV) went to produce the Season One set, they discovered that all of the mag tracks (that make up the audio on the first season episodes) had already been digitized, so the company didn't have to take on the cost of doing it themselves in order to create new 5.1 audio mixes for each episode (in addition to the original mono). However, those tracks haven't been converted yet for Season Two and the high cost of digitizing this material has caused the budget for the BD production to become quite expensive. Network has informed me that they're definitely committed to releasing the season on Blu-ray and they're talking with ITV and New Video about the best way to make it happen affordably while ensuring that the set is of the same high quality as Season One. As with that set, Network will transfer all the episode film elements in full HD for remastering and hopes to find additional film material in the archives as well (outtakes and the like) that they'll also scan in HD for inclusion on the set. Of course, they again plan for the audio to be available in both 5.1 and the original mono. That said, the time needed to work out these details and complete the production properly means that Season Two will likely not street on BD until late next year or early 2014. In any case, rest assured that it's coming... just not right away. Adjust your plans accordingly.
