Interesting... It looks as if Varys might possibly be going with Tyrion all the way to where Danny is in Meereen. I suppose that could work, considering we don't see him hardly at all in the final two books after he helps Tyrion escape. And they appear to be completely removing the Young Griff/Aegon subplot from the show version. It's almost like they specifically brought attention to that point by mentioning "her, not him". I wonder if this means that the whole Griff subplot in the books has been a red herring/dead end all along, and Aegon's army will probably get smashed in the first pages of TWoW. I'm wondering if some, if not all, of Danny's potential suitors will likely be written out of this version too.
It also looks like we might be getting a glimpse of the "Brazen Beasts" here, with the brass masks, although they all look quite similar and decidedly human and not unique animal faces. Probably easier to mass-produce on a budget this way.
Nice to see Bronn is still being involved and didn't go off permanently with Lollies. Should be interesting to see how this plays out with him and Jaime down in Dorne.
REALLY looking forward to seeing Alexander Siddig, although I don't recall seeing him in this trailer.
