I'm still thinking (hoping?) that the delay is due to some incompatibility and Canon want to avoid further egg on their face. PreProd models are out there, and nothing significant has been reported, so would guess it is something to do with an add-on as this site reported.
I would be surprised if Canon are not loaning pre-prod models to press agencies and the like so they can get used to the camera and thus buy en-masse when the Prod models are released, with an appropriate "thank-you" discount.
UK CPS members have not offered any advanced orders...
Anyone know what discount Canon Canada gave CPS members off the list (Rob Galbraith reported significant)....
