Why? The new AirPods still have Hey Siri and longer battery life on telephone calls. If you choose the Qi case they still charge wirelessly with other Qi chargers.
It’s a solid spec bump to a product. Not a huge leap (which is there is no 2 in the name) but it’s not like they were ONLY going to work with the AirPower and had no other new features.
No reason to cancel them.
