I am calling it and saying this will happen with the next gen systems. Of course they still will offer physical copies for people with shitty internet or that just like buying physical copies but digital just makes sense.
It's cheaper to distribute. You don't need a middle man retalier to offer it. You could realistically offer your product for cheaper therefore possibly moving more copies and end up making more money. Also, you can't trade in a digital copy so it elimanates that part of the market. All perfect if you are a dev/publisher.
As a consumer you have a digital library that is easier to access and manage and you get your games cheaper. Also, you get smaller devs taking risk and are actually abl to get their games to you.
Xbox sort of already has the latter with Indie Games and the Arcade and I know PS offers SOME titles as DD on relase day but I think this all will be industry wide.
Even Gamestop is pushing it's digital distribution these days. LINK
Win win for everyone? After using Steam the last few months I say yes.
