I heard about it a few months ago on this mountain bike blog:

According to that post, it looks like here are the changes from the Contour GPS to the Contour +
Wider Angle - Shoots 170º up from 135º currently
HDMI out
External Mic port on the bottom of unit
It will have the bluetooth connectivity use the IOS and Android connect view as well.
I will post again once I hear exact details.
