From all that's been gathered, Sony is making a modest profit on each PS4 sold. They've said this in a few interviews. They can't afford to go into this losing money like last time, that was part of the design from the beginning.
Sony and Microsoft are anticipating that consumers will transition to buying digital over physical this gen, which eventually renders a lot of the disc discussion moot. They're both in good positions to do this, and policies regarding ownership and perks will evolve as the generation plays out in order to entice more folks towards building game libraries on the HD instead of on shelves.
Sony having consumer friendly policies when it comes to physical retail doesn't impact that long term strategy, and it's great PR in the short term (along with being the right thing to do).
