Despite that you can play as Corvo, I strongly feel that Dishonored is going to showcase more of Emily than him, which in my opinion, honestly wouldn't be a big of a deal because I like Emily. Even as a kid in the first one, she showed that she's not this dainty little orphan. Clearly she's the kind of kid who wants to be a strong character, this is like what people like Anita want to see more of.
But you know, because you can also choose as a guy to play too, it's completely overlooked and it has to be a goddamn problem.
The way that the trailer was shown at Bethesda's conference, it looked more like it would focus on Emily and her regaining her rightful throne.
I didn't even think that Corvo was even playable until they finally said something at the end of the trailer.
Harvey Smith and Raf Colantonio even said in the interview afterwards that the main focus was on Emily with her new powers, while Corvo would be there with different powers.
