Unfortunately considering how many of these gamers are willing to pay extra $30€ just to get 1 week earlier access to a game, I'm afraid you are wrong in this regard and we're going to see prices go up even more. Piracy is also dying, either because of groups disbanding or getting sued, or because of DRM getting better and more widespread, and once that is gone it's going to let publishers jack the price even higher up.
I'm pretty much resigned to just play indie and AA games at this point, there's no way I'm paying 60 or more for these broken, bloated and often overpriced products. There are few exceptions but even they will be driven to higher prices eventually.
