A lot of $60 games don't get any additional content. You get what is listed and that is all. Currently we have gotten all that we were told would be included. So you haven't been blocked from anything, any more than someone who didn't buy taken king doesn't get to join in the king's fall raid. What's more, no matter how many people buy the taken king you won't get the raid if you don't buy it yourself. Now we have a handful of cosmetic things being introduced. If other people buying these things makes it possible for me to get extra content added at no charge to my game... That is a win for me. Maybe bungie will blow it. Maybe it will work to all our favors. Either way you aren't blocked from anything you paid for.
