I'm covering the Sony WH-1000XM6 and speculate why we haven't seen it. I believe Sony is analyzing the current market, trying to understand if they should launch one or two headphones, or keep the XM5 available with the XM6. The acquisition of Audeze is likely another reason we haven't seen them announced. Audeze's planar magnetic drivers could offer improved sound and noise cancelling. It is likely Sony's engineers are still working to make this new driver a permanent part of their new product line.
