Just wanted to chime in and share my opinion on AF Point selection Joystick option for 6D Mark II:
1. For people that Focus and recompose all the time ( I shoot with 2x 6D originals), joystick or not - it makes no difference for the obvious reason. It won't get much use.
2. For people that utilise full spectrum of AF points available and shoot over optical viewfinder professionals or events, run and gun, PJ stuff, wide open with fast glass, etc... - AF point selection joystick is imperative to have. I argue that it isn't practical to use a camera without AF point selection joystick as a backup, unless you shoot with second camera with slow glass, stopped down or in live view on tripod with plenty time to compose your shot - landscapes, architecture, macro, food, etc.
Now, taking in the account that 6D mark II will likely be released with 40+ usable AF points, I do not see myself upgrading unless there is a tool to manage all those points provided when I shoot over optical viewfinder. I need to be able to switch between points in under 3 seconds whilst still controlling the subject over the viewfinder.
Failing that, I am good with the 6D original until I switched to 5D bodies when the price settles later next year.
