So I understand it's pretty common practice these days to remaster new DVD releases of older films in HD. So why is that the studios don't release a simultaneous blu-ray release? Is it really that cost prohibitive to manufacture blu-rays? The new Wolf Man special edition from Universal looks great, the movie was obviously mastered in HD...so why didn't Universal release a blu as well? Sony has lately been giving us some great catalog releases. The movies in the Film Noir set look great, but why was there no blu-ray release? If they've gone to the trouble of mastering the films in HD, then why don't they just give us a blu-ray as well?
