My prediction for 4.3 (Obvious Spoilers)

[Mieck]

I've been interested in Asahi's dialogue in the trailer - about striking an emissary, and giving into anger.
Are we, the Warrior of Light, responsible - at last - for what comes next? Is it our "mistake" - slaying a high-ranking Garlean citizen simply for revenge, that leads to imperial reprisals?



Incidentally, striking an emissary is a nice play on the first meeting between Minfilia and Elidibus. I suspect it's unrelated, and just a nice parallel.

Hidden stuff, because it's not strictly 4.3 lore related, but I think it has potential to be related to the plot.

Also, Yoshi said in a recent live letter (I think the one before last?) that they are sitting on a new form of content that will surprise people (I am paraphrasing from what I remember, and can't look up at present). If they haven't said a word about it yet, then I think it likely that it ties into the plot.
Edit: I've found the source, it was a Reddit post relating to a pre-4.0 release interview, so it could be that this was all parcelled up in Eureka, although Eureka had a name from the start, so could be that they still have something up their sleeve.
