Most excited for the new main camera sensor (if the rumors are true) but also the action button.
I made a shortcut today for controlling the lights in my room that I plan on assigning to the action button permanently. If the lights are on, it turns them off. If the lights are on but it's past a certain time, it sets the lights to a dimmer orange color which I prefer after sunset. If the lights are off, it turns them on to my preferred color scheme depending on the time of day.
A magic light switch, always accessible. No more fiddling around with different Home 'scene' buttons in a widget.
Ideally I'd like some kind of ultrawideband system that changes the button's action depending on where I am in the house. If I'm in the garage it should open the garage door. If I'm in my lounge it should toggle the lounge lights. et cetera et cetera... GPS support too, so the action button turns into the media play/pause button when I'm away from home.
