I'm more curious about the sensor performance, particularly its low ISO dynamic range. If Canon shows no improvement in this department, it's unlikely we'll see anything better coming out of Canon sensors in the next 4 to 5 years.
This is a good example of why we should be oh so concerned about sales figures. Canon has been behind in low ISO dynamic range throughout their sensor lineup for a few years now, and it hasn't hurt their dSLR sales.
If the roof on your house looks to be in excellent shape and doesn't leak, would you replace it? Unlikely…if it ain't broke, don't fix it. From Canon's perspective, their sensors 'ain't broke'.
I respect your opinion, but I have to disagree with the "if it ain't broke, don't fix it" mentality. Canon is basically a tech company, and if a tech company is being innovative, then sooner or later they are going to be out of business. I also don’t think you can look at current sales to determine if a company will be successful, or profitable, in the future.
For example, take a look at Blackberry or Nokia, these two companies not too long ago were the 800 lb. gorillas in mobile phones. They had solid sales numbers, and now they are struggling to survive. I’ll bet when those companies were on top, their management was saying, “if it ain’t broke, don’t fix it”, and now look at the situation they are in.
If Canon, Nikon, Sony and the other players don’t continue to deliver innovative products, then sooner or later they are going to be the next Blackberry/Nokia.
Just my two cents.
