Hey, I've got this brilliant idea. You either don't get a PS3 but instead get a PS4, and as a result, when you get the streamed games, they're new not rebought. Or, you get the PS3, you play the PS3 games on the PS3, and you play the PS4 games on the PS4. I know this is a new concept but I have this sneaking suspicion it will catch on.
Because this is Sony and I doubt they'll let Western gamers just confirm their games for streaming to their console. Even if they don't, you'll probably lose all save files and God help you if you still are hoping for a decent MP experience on a streamed game.
