It's official in the US too:
Curious that Canon states that the issue will be addressed by a firmware update. Have they been aware of this problem for some time and already determined that it is not hardware related? To a non-engineer such as myself, it certainly appears more like an image latency issue than a software issue. Of course, if the problem is tied to the speed with which the sensor can be fully cleared of a prior image, the firmware "fix" might involve throttling back the maximum available frame rate based on selected shooting parameters. I'm sure Canon doesn't even want to think about a recall. Let's hope the ghosts really can be exorcised through a firmware update.
It will be interesting to see how this story evolves.
