"I think there's a way that retailers can participate in the digital market. They have to choose to do that, they have to work to do that, it's an evolution. And unfortunately like any market force if people don't evolve they can be left behind." - Ubisoft's Chris Early
With the way things are right now, GameStop has shown how to be successful with this. If we get to consoles that are download only and block used games, I'm not sure what retailers could do.
