Companies have the irrational concept that most people who buy a game used would have bought it new if the lower-price alternative didn't exist, and that's basically why they want to eliminate the used market. It makes no sense and I think the main console manufacturers know that, but it has to be conveyed to publishers somehow. The easier solution would be to reduce game prices across the board to make people more willing to buy games new, but that's not gonna happen with the constant increase in production costs and completely ridiculous number of copies games need to sell in order to turn a profit (example: Dead Space 3 needs to sell 5 million copies to not be a failure for EA... that's not far from what the first 2 sold combined, for comparison).
I wouldn't say I fear the digitization of gaming, but rather I fear the idea of giving game companies more power than they should have in regards to how much they charge for games since going fully digital means there's literally no alternatives other than hoping the publishers drop their prices. It can get to a point where games become too expensive to buy in general, and I don't think anyone wants that.
