This is exciting ehehe

I love those conspiracy theories... and why not speculate ? This is a "Rumors" site after all

I believe too CR is a good free marketing for Canon, no point in taking it down.
Those leaked pics could be inside job,very good timing just before D800 without revealing too much details either.
I have another theory, more simple but less likely:
My guess is that those pics are from the same batch than the "somewhere in africa" ones before. Same 1DX/5DM3 combo, same vague location but definitely with big blue sky and a lot of sand around.
What marked me in those pics before was the photographer wearing a Ricoh GR scarf, which could be odd if the guy is Canon staff and this is a PR photo op. Same goes for the Sigma lens on those new pictures. (ok, that could be on purpose to "prove" that it isn't a PR move...in this case i would applause !!

)
Maybe one good move from Canon would be to give their coming camera to field test to photographer who are NOT Canon fanboys expecting too much from the 5DM3, so they give objective opinion AND are not too keen to "leak" any details on rumors site because they just don't care that much. So no need to take a picture of any new feature or button, just a couple of front shots would be satisfying.
And they would be more likely to keep their NDA than anybody like us ahahah

That doesn't explain MichaelCruz though....argg this is exciting !
