The trailer had a lot of interesting things to so and quite a few possibilities left up to interpretation. Rather than making things clearer it just raised even more questions. I suppose the trailer did a good job of not giving way too much so they could be properly answered in game.

I'm still kind of wondering why a threat of a calamity of light would be occurring. Have our successes been enough to tip that scale? It seems weird to me since it's been suggested throughout the game's story that Hydaelyn had failed nearly every time to stop the tide of darkness yet it's a threat of light that seems to be the main thing focused on now. We know the Voice speaks of the path leading of a calamity, the question on why this is still lingers a bit on my mind as I think about it. It's probably because prior to 4.4 there wasn't really an indication that the balance was off in that way. There is definitely something more going on... and I can't even begin to guess what it is right now. It's going to be a long way to the 8th and an even longer waited if it is not answered in Part 1 lol
