The reason the new content is free is because it's based upon the old content. Meaning we have already paid for what we are about to get albeit in a new variation. As a gamer if Bungie would of tried to sell previous content that you had already purchased how would that have gone over? It's still TBD exactly what this latest update will provide in terms of actual brand new content. Hence the Bungie hype about the Twitch streams. I'm glad there will be something new coming to the game but I'm realistic and not expecting that there will be anything substantial. You get what you pay for. We are getting updated content. That's what's coming.
