interesting, it is nice to get your reasons, I can't decide if AF point are the new mega pixels!
The number of AF points is not super critical, more important is accuracy, speed, tracking continuous AF etc.
We wont know what real improvements Canon has done before these get properly field tested but there doesn't seem to be much difference to the 1DX.
I kind of agree with Jase, not a particular big jump but we have to see what that sensor can really do. maybe the sensor gives 1 stop more clean high ISO shots and 1-2 stops better base ISO.
18->20MP is not noticeable.
12->14FPS is not noticeable.
I think it all rests on the sensor.
