I haven't seen anything to indicate the headset requirement has changed on the 2025. Wireless ACP and AA is a good thing but that's a seperate issue altogether.
Just remember the headset (microphone) requirement is a demand put on by Apple and Google as a safety measure. They don't want you driving distracted while pressing buttons or twiddling knobs on Apps running on their device. They would rather you be using voice commands. It's no different in your car except your ACP capable car has a built-in microphone, your bike does not.
As far as I know, you still need a BT headset or dongle to inform your phone that a microphone is present, even on the 2025 model. A wireless connection doesn't change that (unfortunately).
