I think arguing about Nikon vs. Canon is a bit pedantic in today's market. Both make exceptional cameras with little discernible difference from the resulting shots for each price/performance bracket.
It also seems that people are so caught up in "gear" mentality that they will argue to the death about specs, but they still take crappy shots and don't worry so much about improving as a photographer.
I would hate to be a Canon engineer and be happy to introduce a budget FF only to have it rejected by forum debaters. The OP doesn't even have a clue about the naming conventions or his comparison would have been that the 5D3 was the 3D and the 6D the 5D3 (and even that would be wrong).
