Reading the posts in this thread and other links provided I'm convinced the next 5D will be called 5DX, will have 22 mp, pro AF and great image quality both at low ISOs and high ISOs.
I hope they will have the multicontroller on the grip as in the posted images from Kenya. This is a must have feature for me personally. I can't tell you have many time i've cursed my 5d mark ii for not having that. Best way to change the focus point with the grip on and holding the camera in portrait orientation.
Can't wait for March 2nd!
