The ' "Art of the Muppets" showing will NBC makes decisions HOLLYWOOD (AP) "*Prime Time Sunday" will become "Prime Time Saturday" around the first of the year, and NBC will cancel two more series. Joining "Eischeid," already announced for axing by year's end, are "A Man Called Sloane" and "Kate Loves A Mystery." The latter series was canceled last spring, then revived for the fall by the network. Among the new shows set for the NBC schedule i is "United States," a look at contemporary marriage produced by Larry Gelbart, who brought "M-A-S-H" to CBS and wrote the movie "Oh, God."
