I don't really have much to say. I'm tired of this.

This sounds like a speculative rant.
I'll wait until the camera is actually released.
I don't want to keep lying to myself anymore, we already know canon. At least, the only 2 things I can see coming is CFast and dualiso hardware integrated.
Its all rumors, but this also came up:

5D mk IVc
18Mp
4K video
5D mk IV
28Mp
(1080p??)
All that matters is that A1ex gets to have a go at it :)
