The 10s video teaser hints of a new Zenfone with dual camera setup over the back. The message says "see what others can't see". It's unclear if those two camera will be used to take 3D pictures, or for better focus and post processing effect, just like in the HTC One (M8).
The CES show kicks off January 6 in Las Vegas, so we'll know more very soon.
