I think it is a 'HOAX".
1. I do not think Canon will have a "EOS 3D" strap to be used on a real EOS 3D that they do not want to be identified.
2. The edge of the strap looks like "flake fur". Will Canon use such kind of material for the camera strap?
3. The Chinese Text says " picture taken at the end of certain year" . therefore the picture is taken at the end of last year at the latest, may be even earlier.
I think someone is having fun with us
