I'm with Richard on this ... I've had my 7D for 5 years and it does fine for me.
I admit I'm getting a bit concerned about the number of actuations, but I'm in no great hurry to get the MII, I'm just reassured to know that it seems to be an improvement on an already excellent model.
At the end of the day though, cameras are a bit like cars ...not everyone is comfortable driving any model, but all drivers are generally comfortable with the one they have at the time.
I still could do with a course on how to use all the functions on my 7D, but I still seem able to capture the kind of images I want to.
