Seriously what is the point? Its just turning into an ISO/Mpix pi**ing match with frames per second soon to be added to the mess.
ISO 102,400 is not a selling point unless your a cave troll that doesn't get out much

I have a 5d classic and try not to go above iso800. I would love a 5D2 so I can squeeze shots in at 1600 or 3200 knowing they will be great but never felt constrained by iso800
Lets just be done with it and all get RED bodies with night vision that shoots with a gazillion Mpix sensor the size of a car windshield at 3000fps and take the stills we like....

Constrained by 800? On a 5D?
