1Ds Mark IV for Photokina [CR1.5]

Is it really?
I've been told that a 1Ds Mark IV announcement can be expected for the Canon EXPO & Photokina. Availability of the camera could be some time after (2 months?).

Canon will make a “big splash” this fall with 3 digital SLR's and a “revolutionary” PowerShot.

Too good to be true?

Steven Alvarez posted that his friend is indeed testing the 1Ds Mark IV.

[CR1.5]?
Yeah, weird rating! I know the source, but they have about a 50% batting average.
