Not if the new product does not sell, or sell in sufficient quantities to maximize profits. It makes perfect sense for Canon to maximize profits. If nobody bought the new flash, Canon would have to scramble.
I'm sure Canon has thought about this, and just wants early adopters to get only the 600rt and for the high starting price. Speaking of maximizing profits, after some month of 5d3 and seeing what people buy it, Canon could also have priced it at $4000 and nearly sold the same amount. Same with the 600rt, I guess.
