My bets are on its an EOS Movie targeted camera(locking mode wheel so it won't switch off manual accidently when shooting video, the movie/live view button, the lacking CA mode on the dial indicating its not geared towards consumers)
The camera is still a DSLR, so it would make sense to make sure it works well when taking photos. He could also be testing how shooting with a widescreen aspect ratio screen in portrait mode is like and if it feels right or if it's to awkward to use.
Also the new buttons on the left side of the screen looks interesting)
