Digital distribution will make perfectly clear, once and for all, the untenable nature of the $60 price point.
Just watch what happens when customers suddenly find themselves with no choice but to pay full dosh for their games - instead of buying 5-7 games for $300, selling them back for $100 more, and buying another 2-3, suddenly they can only buy 5 games for $300, end of story.
No used sales, slower descending price point (watch what EA does with its $20 digital copies of five-year-old games!), fewer sale opportunities, no money back - ever... and much harder/less attractive gift giving.
What will happen as a result of this?
1. Sales turn down (slowly at first, but faster over time as retail dries up) for all but the biggest games as people are forced to choose which purchases to cut.
2. Consumers play fewer games and have less fun for their money.
3. In an attempt to stem the leaks, lesser companies and lesser games from major companies will switch to offerings at lower price points,
4. making the big games look just as overpriced as they are, leading to either
5a. the big games being forced to lower their prices to survive, or
5b. the big games simply dying off.
And throughout this charade, the B-list publishers will keep selling their $20-$40 titles - mostly on PC - which will be looking more and more attractive to a cash-strapped populace. And, of course, the Steam sales will continue.
