Time will tell, indeed. TV trends change. Technology changes. Ways of doing entertainment changes.
These days, things from the past tend to come back with more force then ever before. I hear Ghostbusters is coming back to hand the packs off to a new generation...and packing a ton of history baggage that the cameras didn't follow with it. Three Stooges is now hitting the movie scene after how many years of time lapse? (Apparently, not as a reboot, either.) So many other franchises to be listed here to bore us all into comas. So, if Knight Rider is ever going to ride off into the sunset is a hard one to predict.
Now, I do note the advancment of technology, here. Perhaps, as public vehicles begin to become more and more auto pilot compliant, the notions of having an action show that revolves around high tech on wheels will become rather dull and outdated, like this Buck Rodgers movie I saw on Hulu, today. Who's to say. Then again, for entertainment, who is also to say that it must be done with physical cars at high priced production values, at all? A future KR show might happen inside an entire CG reality with minimum expense and at a writer's level of creativity. Sure. There will probably be a million posts about how 'non-reality is garbage' and how real cars better be getting crunched up for the show to be good and bla, bla, bla...viewpoints have enough room to be seen from many angles. I, for one, can go with nearly any angle...just so long as 1/16'th sized models with five LED's aren't sinking into some black mush substance, looking about as un-realistic as anything.
Hey, look! Top Gun is getting ready to be released on X-Box 360. That makes about...what??? 50 video game versions (Probably closer to 30, in reality) for a mid-80s' movie with zero official sequels, now?
