Well, do take into consideration that Pentax used to be bigger than Canon, at least as far as SLR cameras go. Not only was Asahi the first japanese player on the SLR market, I've heard it was the fist company worldwide to sell 1 million SLRs back in the sixties.
But yes, gone are those days and while Canon won't be big forever either, likely the market won't change that much in the coming few decades.
