So now it's a <$170 device that has optical HR and GPS. It may not have some of the Garmin features (ANT+ is a maybe, GLONASS isn't included), but it adds a headphone output, connectivity and I suspect it will ultimately have a stronger app ecosystem.
If they've implemented optical HR well, it could be a very compelling alternative to the less specialised Garmin devices.
