The CDJ-1000MKII is solid and reliable but in my opinion lacks innovation and modern features and I think I prefer the moving platter.
That's your opinion, it may sound rude. But the sales of these machines are so high, i'm sure Pioneer wouldn't have expected that.
The machine is very well sold, and I guess that's the main reason why it isn't replaced yet
Same story with the Technics TT SL-1200MKII, that one wasn't replaced to, untill a little time ago.
