I think shows of that type have a bit of a shelf life before they don't quick work anymore.
Thoughts?
The fact that the 70s version stayed for so long and no version since has touched the hem of its episode count is a testament to how impressive it was to keep it going through 1982. It's hard to consistently write material that plays well and assemble a solid cast.
I don't ever see the show reaching its 70s popularity, but I could see the networks dusting it off for primetime spurts ala ABC every decade or so.
