This is brilliant! Even though it's at low-resolution, you can tell they tried very hard to put the dark look to it.
So this is the official trailer right? Or at least part of it. If so, then I'm sure a high-resolution video will soon be out. After all, only about 3 months left now.
Edit:
I just saw Emma's update, and as long as they're working on it, I'm more than happy. I'm really really excited for this! Yeay!
