I had read about Norm retiring from NYW a few weeks ago but just one report. It also said that he may do one off specials from time to time (maybe things he makes for This Old House). The new season of TOH that started last weekend has an 'interesting' new intro where Norm walks into screen and says, 'Hi, I'm Norm Abram and welcome to the 30th season of This Old House'. So it is still possible to get a fix of 'Norm'!
As for repeats of NYW - they don't seem to be showing any at the moment - there are certainly some episodes I would like to get decent quality recordings of, but there seems to be this tendency to move away from information/instruction and focussing on personality instead.
