I agree, a European price of €4.500 doesn't mean it will have an MSRP $5,600 in the U.S. I doubt the street price of this camera will be much above four grand.
Also, I'm shocked that Canon stuck to USB 1.1 and IEEE1394. With this resolution and frame rate, Firewire 800 is almost required, but even USB 2.0 would have been a welcome addition. For a camera clearly aimed at photojournalists, especially sports photographers, such a workflow bottleneck is almost unexcusable.
Firewire 800 and/or 802.11g wi-fi in this camera would have rocked the world.
