There is the SZ2, but as it is already out of production, I believe that there will be no more updates from Pioneer for this equipment. It will continue with the new line DDJ-200, 400, FLX6, 800 and 1000/1000SRT range.
DDJ-SZ uses Serato and this is terrible for detecting BPM and fitting the grid to the music, especially if the music is not EDM. I've been using Serato for 12 years and it's been the same problem since then.
Tip: turn off the grid and orient yourself by the waveform's peaks. It is much better. Grid just gets in the way. But doing that you lose the SmartSync, Quantize, Beat Jump and some features of the Pad that depend on the grid to work. Take a test.
