I sincerely doubt they'd do that so soon. Maybe the next gen after this one.
Yeah, I bet they give you a choice of physical or digital and then slowly phase it out to just digital.
In some ways, I like having digital. No having to get up from the couch to switch games! No need to worry about to keep the physical packing 'pristine' to re-sell.
On the other hand, All Didg, No Phys means you can't do any re-selling or trading, and you won't ever be able to pick anything up used on the cheap.
Books, however I prefer physical. And used. Why pay $8 for a new paperback that I can find used for $3 or $4?
