My 7D continues to be available for service, and continues to take decent pictures. It will keep fulfilling that role until something comes along to justify the upgrade. Until that time, no sweat from me.
Speaking of the 7D InsanityBeard, can you tell us if the version 2 software improved things like noise at higher ISOs, colour rendition or dynamic range at all?
I cannot answer this I'm afraid, having read some people's stories of the camera locking up or some AF issues (I think) after installing the version 2 firmware, I have not done it myself! The camera continues to operate with the firmware it came out of the box with. Perhaps somebody else can answer your question.....
