I got all excited thinking it might be f/8 focusing
Same! Although it does explain why my camera kept having strange issues with the time. I think I must have reset the time like 5 times before it actually stuck, before that all my pictures were "taken" 4 hours before they were actually taken. Sadly it didn't work like a time travel device, although it was aspiring to be one.
Hoping they still bring out f/8 focusing, given how well that center point works in the dark, I don't see why it can't handle an f/8 lens (although I don't know enough about AF systems to know that for a fact).
The biggest annoyance I have is there doesn't seem to be a way to set the shutter speed to 1/180, unless a speedlite is attached, meaning my studio work done with dumb triggers has to be done at 1/160 even though 1/180 is possible. However I don't think that's something Canon will care about fixing, since they have a solution - buy 4 Canon 600EX-RTs....
