Here's how I see it: if you are a true fan or just like the game more than others you'll buy TTK no matter what price and if you're not, you'll move on to another game and either come back or stay away. With the amount of content shown so far, I think it's worth it unless something dramatically changes between now and September. People are are going to leave, come back, and just start Destiny in September. Just like most sports there's too much time on the clock to tell what is going to happen before we can come to a conclusion.
