GLA's "Coming Home" Feature

I know this aspect of the Mercedes GLA was revealed with the concept model but does anyone know if the GLA will come with this "Coming Home" feature? Basically "Coming Home" allows the GLA to acknowledge its approaching driver by pulsing its blue lights, letting the driver know the car is "ready" I guess. The lights normally function as daytime running lamps, but act as these "Coming Home" lights when you're on your way to the car. I also remember reading that the air vents inside would change color depending on temperature. Any word if these features will last, or were they just meant for hype, like the laser headlights (unless we are actually getting those...)?
