It turns out that the WH-1000XM6 will be official later this month after all. With Sony remaining quiet for now, a major retailer has revealed almost everything there is to know about Sony's WH-1000XM5 successors ahead of time. The leak sets up a possible simultaneous release with the Xperia 1 VII too.https://www.notebookcheck.net/Sony-WH-1000XM6-and-Xperia-1-VII-doubleheader-release-mooted-as-official-specs-and-pricing-for-new-over-ear-wireless-headphones-spotted.1009927.0.html
It makes perfect sense since Sony does bundle their XM cans with the Xperia 1 phones.
