Now that we finally got the trailer there are a lot of questions. We tried to summarize all the information we have to write a more or less complete analysis of the trailer and a collection of all our theories (which can proof right or wrong) that came up during watching the video.
Please keep in mind that this analysis may contain spoilers. If it’s a major spoiler we marked it like this: [1] and will put the spoiler to the end of the entry so you can either read it or just leave it by that.

If you also have some theories and ideas, please let us know in the comments as we would really like to hear them.
