...but if they were trying to keep it secret then why would they make a strap for it instead of just a standard canon one?
Another question to ask: why did they blur the camera but not the strap??
I think the answer is that they were intentionally leaking the camera.
The Sony A99 was leaked this way - by first leaking a photo of its strap.
I vote that the 2D/3D is real and that this is an intentional leak
We are likely (very?) close to announcement.
