You can either use the Turntable View or the Waveform view. However, it is not possible to get the Waveforms displayed on the vinyl platters.
This is not a new feature. The video just shows the track Waveform overview that is above the Turntable. Sorry for the misunderstanding.

This link brings you to the video for Djay 2 for iPad and 21 seconds into the video it shows a waveform on the vinyl of the turntable. How do I turn this feature on?
