Actually Monty said there was foreshadowing in the songs and he said he already knows where he is going for the next 5 seasons. As for whenwere the trailers done... all in the past. Weiss you see her get her scar in the trailer and she has that scar in ep 2.

Now as for getting new songs in other volumes, even the new song won't invalidate those already out!

It's funny how people think because we've seen only volume one it's impossible to predict too far. Season 1 will be exposition for the next 5 years. Oh we'll get some surprise later but basic exposition is already half out. If you know most of the world's rule then your basic storytelling techniques will tell you a lot. I'm pretty sure the specific in my tales are mostly wrong but i'm equally sure that the basic tendency overall is right. And I even may have some specifics right!

All I can tell you now is see you in 4-5 years and let's see who's right.
