If they use the same prints as the Universal DVDs, the first portion of the first season will have the original main title theme. While not iconic, it's still a very nice tune that fits the show very well.
The Universal TV shows I've seen have been fine. Knight Rider and Airwolf look great. If Magnum goes the same way, I'll be happy to buy it. I'll just wait for others to pony up before I do.
