I'm not brand-loyal (bought Canon, Nikon and Fuji) but to me, Canon's appeal over Nikon since Nikon started their unilateral pricing policy 1 year ago was the fact they allowed their authorized retailers to offer deeper discounts, particularly over the holidays. It's one of the factors that made me sell my Nikon gear and move to Canon this year, despite my feeling that Canon was behind in the tech curve and overpricing their new releases. Now that Canon's implemented this, I don't see see any reason to continue buying Canon.
To me it's like when Sony dug their heels in when Samsung started eating their lunch in the video/audio electronics market. Their approach was to go conservative with product development and keep prices high. Now Sony is reeling and Canon is in the same boat. I'm not against unilateral pricing per se (all of the major electronics corporations are now doing it), but Canon is going to fail unless they put out more compelling products to justify the price increase.
