Picked one up in Henry's last night.
So far so good, can't find anything to b!tch about (maybe except rather cumbersome Autofocus selection - the zones, Auto point selection, single point selection - requires pressing to buttons simultanously. not a biggy coming from 1DMkII where single button was mostly for shutter only anyways 
)
Tried some high ISO's and they are really usable. Daylight shots - took some buildings, sea gulls and stuf in Toronto, will try to post later on today.
