I respectfully disagree on the elimination of used games being a negative trait.
Yes it is being done for profit, but done for a
shift in profit. Every used game sold is one copy of a game that will never net a profit for the developer.
Going back to my earlier Steam analogy, the reason they're able to offer such awesome sales on major titles is because they're minimizing delivery cost, and eliminating the chance of used games.
I know it's a long shot, but I for one am optimistic on this being the opportunity that consoles need to reduce game costs, maybe not initially, but in the form of digital sales and price reductions on games I want to play, but don't get when they launch.
I know my thoughts were all over the place on that, but Penny-Arcade's Ben Kuchera sums up what I'm getting at very nicely:
