I bet there's a small chance, like 1%, that Sony is simply patenting this specific process to keep anyone else from doing it. #conspiracytheory
Honestly, I don't see them implementing this. If they did, it would only affect me with older games. I just recently picked up FotNS: Ken's Rage, but I could only find it used. And I'm one of those weird people that actually likes Gamestop, because the employees at the stores I've been to are awesome. I realize some people are kinda poor and don't have the money to buy games new, and others are just cheap and don't think anything is worth full price, so used games have their place. While I don't agree with them doing this, since I actually do loan out games to my friends so they can try before they buy (especially when there is no demo available), I understand why they might be considering something like this.
