I doubt that they will jack up the price of the Blue Ray DVD's and players, they are still trying to attract people to the format. If they can capture half the people as they upgrade to TV's that can view HD (even if it isn't 1080p) then they willget the mass of people to start making the players come down in price due to the amount of sales they would receive.
