Just talked to a buddy of mine who owns an audio store in Madison Wisconsin, he said every year Technics talks about discontinuing it but never do. Maybe in Australia yes, however I don't see them discontinuing it in the US.
BTW, I love my Technics, I think it is one of the best pieces of electronic equipment ever made by man. The design, ergonomics and ruggedness of it are top notch. The only minor issue I have with it is the RCA cables, those always seem to shit the bed after 5 years or so.
I appreciate gear that you can pass down to your kids, most of these plastic midi controllers and laptops won't be shit in ten years, however the Techs will still be going strong.
