I don't know how I would feel about it IF it actually happens, patents area dime a thousand.
And it's not like the used games market would dissapear under this new system, your authentication key would have to be managed for the new user, but that's it.
The only thing that gets 'used' with a used game is it gets put in a drive and someone touches a manual, it's not like the data on the disc becomes unoptimized with use or anything. At worst there might be a scratch or two, and if its so scratched that the game won't work, the person buying a used game should know the risks in that case. 90 percent of the time the disc is fine anyway, and when bought at EB or whatnot they o check to make sure the used games work.
I'm not saying that consumers don't have the right to be oportunistic cheapskates, but it's BS the way the the money is distributed from those sales. I don't buy used games from stores for just that reason. I think a more controlled system (not as controlled as Sony's limiting the buying and the form of monetary exchange) that ensures some of that money goes back to the developers is a good thing. There are plenty of developers who aren't EA.
