they show them during a brand new keynote where they have always announced new hardware.…no one is saying these are different AirPods Pro 2 models. We all understand this is a new software based feature for an existing product.
I had several friends text me that they are ordering the new AirPods Pros and they already have them, so I had to show them enough info that they decided to cancel the orders, that was just 5 people that I know. So try to imagine the general public who just see's an ad and believes it is newer than their current devices. Apple is known for yearly updates on products so it isn't out of the ordinary for many people to think these are new.
I doubt "we all" applies to "we all".
