one person new about it though fo sure
I think if your a real fan you at least know its coming .... but my brother has been completely spoiler free and when he saw this trailer he was blown away and thought it looked incredible.... he is alot older than me and was a huge OT fan but was really disappointed with Ep1 and 2....
so what I'm saying is that I don't think the general public knows what is coming as far as how dark, and in my opinion, how incredible this movie looks ....but they will soon know, I'm sure the marketing machine is getting ready to roll out with almost two months to go now
