The most recent estimates are from EA, saying about 30% of full games to be digital currently. That's up from I think 20% a couple of years ago, and 10% a couple of years before that. Then there are all the DLC and MT sales on top of that of course. While it's true the pubs get better margins from digital, they still need that 70%, some of whom will also be buying BF1 season passes etc. All I'm saying is, if you removed all retail stores overnight, game sales would crash. I think there's no doubt that just as more places to buy games is bullish, fewer places to buy games is not.

Console digital sales have no guarantee to work on the next console cycle, and they have essentially no resale value even when selling the console. For example all PS3 digital downloads only work on PS3, not PS4. Steam is fine, within reason of course with regards OS requirements for older games.
