I think the reason that people are "defending" the rumor is that it makes sense. A replacement for the 7d is due. It is the rumor forum after all.
What evidence do you have that the rumor is false? You seem more certain that its a false rumor then the the people who believe it's true.
I think we are at the point where there has to be some evidence presented that the rumor is true, since photographers have been at this event for over two weeks. And how exactly can one "prove" there are not 7D IIs in Brazil? I think it is time for the 7D II to show itself or quietly slink away.
