Games are expensive at launch, but prices quickly fall down. Take Nier Automata for example, a highly awaited AAA game. On launch day, it was $60 at retail, $60 at PSN yet around 52 usd at Steam. Not much of a difference, but wait a couple months or the Summer Sale, and it will probably go for 20-30 usd tops. In such a timespan, it will hardly go down in price at retail or PSN, if at all.
