They sold consoles at a loss to begin with, they overcharge for games to make up for it and people ‘happily’ paid it. Just because they cost less now, they still need to make up for the loss they accrued when they were selling at a loss. When they truly break even on the costs, why would they lower the price? If people have been paying $70 for new games, why would they drop the price when their costs go down.
