The series (except for six episodes) was shot on 35mm. As such, it could benefit greatly from a high-definition transfer. And high-def transfers have already been made. They were the source of the more recent DVD season box sets.
If it's on Blu-Ray, I'm there. I already have The Prisoner
, and am going to invest in Star Trek
(1966) soon. With The Twilight Zone
, it would mean owning the three most important science fiction series of the era on high def. And that would be pretty cool.
