That sums up very nicely what seems to be happening indeed.
Canon has proven time and again that they are masters of the 'long game'. And they probably have a road map for things 3~5 years down the line for this too.
You are right. They have proven the web-based self-appointed smart-Alex camera critics wrong over and over and over again. Digital Rebel cameras too small to be handheld? The 5D and 5D2 cameras will be major failures? 18 MP APS-C sensors too densely packed? Pfffft... what do web based self-appointed critics know?
