I just hope that SE did choose the sequence of the speech on purpose so that we think that Urianger is on the other side. Because if its true than they just would have told us an important part of the patch so I still hope that he tells this to Elidibus, maybe after finding out that they nearly killed Alisae?

But its true the German trailer is quite different. No signs of betrayal and the last part is about the trade of a soul for a world. So maybe they were promised by Elidibus that if they kill us they will get their own world back? So they are kinda fighting for a good cause but the Ascians are just using them to get rid of us? I mean they catch us, tell Alphinaud (in the German trailer) to step aside and after that raise their crystal. Maybe we are the soul they want to use as a trade-in? Or maybe they want to save this world but were told that they need our soul for this? So they would do anything thats necessary to safe a world. Or one of the party members was saved and as a trade they have to end this world.

Hopefully we are not just standing there helpless. X_X Let this end with a instanced fight where nobody truly wins (three vs. five is not a good balance) and its end with departure of them..so our character would not be too strong but also not suddenly weak..
