I dint think the figures show the whole truth. I think digital sales are up mostly due to store sales and offers not day one purchases of brand new games.
It would be nice to see a breakdown of digital revenue split between brand new games and games bought on sale.
I'm 38 years old, love my physical media simply since I can trade it and get some credit back for my next purchase. However, PSN sales have been so good, I've bought more older games this gen than ever before.
I wonder if this is just me, or if this is so common it makes up a chunk of digital revenue.
