Expectations are a razors edge. Also, game production is not a simple or straight forward endeavour. It's not a trivial task to create more content, but it's worth noting that much of the point of the endeavour that is Destiny is to release content regularly. As of now the production schedule is every three months, which is a very ambitious schedule. I fear asking or expecting more from Bungie is a bit harsh, and bordering on ignorant. Though I know you don't mean to be. Game production and the realities therein seem like a black box to us, the laymen.
