Sure it could.But it wouldnt be the same as selling the actual game in a physical form.We need to wait to see if this is true, but when more than 85% of the sales comes in some physical form, I dont think Nintendo is going all digital.They may be unpredictable, but not idiots.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
