This one showed up here on CR many months ago, and IIRC, the guy that created it soon admitted that it was done as a university multimedia project.
I.e. it was done as a fantasy piece and is not a real Canon advert and has nothing to do with any "real" 5D3 that might be released at some point in the future.
I.e. it's not genuine.
(If my memory is not failing me.)
EDIT: Yep! See this thread on CR: http://www.canonrumors.com/forum/index.php/topic,1223.msg16714.html#msg16714
