Hello mate. Pioneer aren't ever going to announce what's coming but if I were a betting man, with regards to the CDJ-3000 (possibly the XDJ-RX3) I'd be pretty comfortable betting that in-built Beatport Link (and Tidal, Inflyte streaming services etc etc) will appear there one day.
There may be a wireless adaptor released, it may use a connector to tether to your phone's LTE / 4G / 5G etc, or even better, there may have been wifi inbuilt the whole time waiting to be activated that has not been announced. I'm just spitballing here though.
Denon's solution tends to work better for mobile DJs but I'm all in with Pioneer (with an XDJ-XZ) as I alternate between club and mobile DJing. Pio aren't going to just let Denon keep taking market share for (generally) mobile / bedroom DJs like they have been.
Pioneer aren't so fast with regards to implementing new/cutting edge software but they do get there over time.
