Aye just read that as well.
It's a pretty interesting setup here. Microsoft will recieve a fee (plus the publisher) from each used game sold, but if Sony doesn't go with something like this (which haven't been confirmed or denied yet), then it will probably make the PS4 more attractive for people that sell their used games. They'd miss the fee obviously, but they might get more people buying the game for their console, which might balance itself out/be a better deal.
It's going to be pretty interesting to see what Sony is actually going to do in regards to this.
