Coming to Blu Ray!
Bewitched will be released onto Blu Ray later this year. The bad news is Sony is licensing the job to Mill Creek, a company known for it's shoddy work. I will wait for the reviews before I purchase. Even if they're only a notch better, it may still be worth the upgrade.
However, if they don't offer the first two seasons in their beautiful, original black-and-white, I'll stick with my DVDs.
