For the most part, most things were confirmed. The current cameras out there are not production models and will be returned to Canon when the production cameras hit the marketplace.
A few did mention that the end of June beginning of July is still the target date, but the quantity will be very small. I’m told a few sports photographers will be allocated the 1D X first. Retail availability in July was mentioned as being “optimistic”. August or September may be the months when big stock numbers hit the marketplace.
