Following the publication of an image on the Amazon.com site showing a drone apparently called a 'DJI Mini 4', DJI have officially confirmed the launch date of April 29 (the same date we snapped from the site), but no specs.
If you visit the Amazon.com DJI store page, you find a picture of a drone which looks a lot like the DJI Mini 2 SE (and, in that respect, the Mini 2 before it – the airframe has seen the spec refreshed without physical changes). Emblazoned on the arm, though, is the name 'Mini 4K'. It is, for now, not a link – it's just a picture; other parts of the page have a 'buy now' button.
