Conpletely digital here. Remember when everyone was mad about Microsoft's digital future with the Xbox one?? Guess what it's coming. Horrible for brick and mortor stores but great for software developers.
Horrible for consumers as well depending on the game. Many games use licenses that they only have limited availability for at which point they have to take the game off (meaning that unless you already bought it, you won't be able to buy it in the future) if the game is a licensed one or if the game uses licensed music, they need to either update the game to take out the music or take the game off entirely depending on if they renew the license to use said music.
That of course doesn't take into account the ability to loan games to your friends, take games to your friends house to play (without needing to redownload the games using your account on your friends console) or sell the games entirely via the second hand market.
And of course, America which is one of the biggest markets also has one of the worst internet infrastructure to deal with an all digital marketplace considering data caps and the ever increasing size of video games combined with the reluctance of ISPs to take away said data caps lead to a lot of trouble at accepting an all digital future with the main proponents from a customers point of view being people who that won't affect and people who don't lend games to people/bring games to other peoples houses/people who hate the second hand market.
There may be other reasons why an all digital future is a bad idea but these are the ones that come to mind and UNTIL these issues are sorted, I don't think everyone is going to just roll over and accept the 'inevitable all digital future'.
Short version: There is a lot of work to do before an All Digital future is likely to happen in a way that works for everyone (apart from Brick and Mortar stores though even they may survive due to the ability to sell vouchers for digital games and wallet top ups which is a thing that happens today as well)
