I personally don't think that I would be too happy with the switch to full digital, and these are my reasons why.
-There are few things that beat the excitement of having a game that your pre-ordered arrive in your hands with all the shiny stuff that goes with the CE.
-When you walk into a store and see a really cheap deal on some game that you always wanted to try but never could afford.
-When you are unsure about a purchase and on the off-chance that someone around happens to know what the game is about and can give you real world unbiased input.
-The ability to buy/sell pre-owned games.
-And most importantly an excuse to just mill about any particular store for a while
