Hmm... yeah there hasn't really been any movement (at least, no rumors lately to suggest movement). They did just release some updated Beats (Solo Pro, right?) but those are on-ear, and Beats branded.
This is what I want more than Airpods Pro-- I prefer over-ear headphones most of the time that I listen to headphones. I'm so pleased with the Homepod SQ that I'm hopeful Apple has something in the cards for this category with an H1 chip, etc.
Maybe this is a 2020 product?
