Update: this just in - it seems that the person holding the camera is associated with Canon.
Those pictures were taken today in New York City - they show an unidentified Canon camera housed in a sound blimp. Now, using a sound blimp (used to reduce the sound of the camera's mirror and shutter) makes a lot of sense if you are shooting at a golf game or a theatrical performance, but on the streets of New York? Maybe they used the blimp to cover up a new Canon camera?
For comparison, this is how the back of the Canon EOS 1d Mark III and 1d Mark IV looks like:
What do you think? Is this a new Canon camera?
Full size pictures after the break. Thanks to Vlad from the PurseBlog for sending those in.
