The 6D should be compared cameras in the same range, not something higher..
If it's about price range, then the Canon competition is the 5d2, which is indeed the real successor to the 5d2 - for the some of the advantages of the http://www.canonrumors.com/forum/index.php?topic=11309.45
As for the real competition it'd be the Nikon d600, but we wouldn't want to compare that to the 6d w/o becoming suicidal :-p
But imho a comparison to the 5d3 is still interesting because it for example what current Canon firmware can offer and what has been cut from the 6d for no reason at all other than marketing / product differentiation, also for example the double-button layout of the 5d2 vs. the one function per button of 60d/6d.
So it's a good thing the outer points are not cross type because it's very hard to move th points using the thumb wheel thing...
Um, you're mixing that up - the outer points not being cross-type is about their precision, not about the physical method to select them. However imho for 9-11 af points a joystick is not necessary and it can also be done with a multicontroller.
