Just wanted to point out to people who are complaining about the zoom button being relocated... you can set the SET button to zoom! And... it is also a better spot for it, I think, because it is easier to hit with your thumb.
Additionally, RECORD/STOP can be set to the SHUTTER RELEASE button (you know, the black one near your pointer finger that we all forgot about ;-)!).
And in closing, there is a CONTROL OVER HDMI setting in the menu so I wouldn't be surprised to be a 3rd party device with an iPhone App (fingers crossed!). I want credit if someone develops that now though!
