Thanks this is very interesting.
Have a look at another quote (one above), seems like publishers are more and more moving to digital only releases. It makes sens for them as they don't like the fact that gamers can resell their games - it's all about the money.
I myself buy physicals version of the game only if I am not sure I will like but still would like to test it myself. If don't like it I just re-sell it. I would say that 9/10 games I buy are digital nowadays.
