They removed because of cost, pure and simple. It has nothing to do with trying to sell more PS2's.
BC would be a great value for the PS3 since, as people already pointed, they could sell it as a replacement for the PS2 saying: "Play all your old games, DVDs and the new games and BR".
Sony would never favor PS2 sales over PS3, no matter how much they are losing. Every PS2 sale today, means a PS3 sale lost for at least one year (next holliday season) if not more.
