Keep in mind that the 
television rights  to 
Knight Rider are not just owned by NBC, you have to get the rights from both NBC, Universal, and Vivindi (not to mention negotiate with Glen) and get them all to agree to sell the rights to another network. While many of these companies are owned by the same conglomerate 
General Electric, they don't all get along under the same roof - case in point, the 
domestic Sci-Fi Channel and USA Network.
Trying to get the television property made by another studio such as 
Paramount , 
Warner Bros, or just for example 
Fox is a massive undertaking that involves more interest to these companies than a simple fan following or demand. When it comes to studios these days, money and greed take presidence over creative originality and passion. It's no longer about providing good entertainment, it's about the investment and the returns gained from it with as little risk as possible.
I don't see 
Knight Rider: The Series pulling a 
Viper and ending up on UPN (now My Network TV in the states) or filming on the Paramount studio lot any time soon. Even if they put 
Knight Rider: The Series  on Sci-Fi Channel for a Season Two, NBC or Universal would still have to flip the bill for production. 
Sci-Fi Channel (It's not Syfy yet!) itself does not fund its own productions - which leads you to wonder why NBCU won't renew 
Knight Rider or put it into syndication but will continue to make horrendous "movie of the week" attempts on the network so bad they're not even fit for a major release on dvd.
I think the deciding factor could also be 
location as many of these incredibly dumb movies are made overseas or in Canada rather than in the states. Perhaps if they moved production of 
Knight Rider: The Series  to Canada like 
Smallville it might have a shot at coming back but then people would cry foul that it's not american made anymore.
