By the time the demand drop rough for them to lower he price, we'll be at year 3 already. If the game even survives for that much longer. Plus, The Taken King will probably be made irrelevant at that point with the addition of even more overpriced "DLC" or rather "Expansion Packs." So the way this works is that they release more "content" that makes the previous content obsolete, so the only real way to enjoy the game is to buy their so called "content" while it's still ripe, because it can and will go rotten pretty damn fast.
