Also, the official screenshot has been released. I'll just rip off the wound now - 720p with no AA. That makes me happy for various reasons, but for everyone else, there's your downgrade.
Well, it's not really a downgrade. Nintendo always releases bullshot higher-res images for their first reveal of a new Zelda. They did it with SS, TP, and OoT3D. The actual quality otherwise is exactly the same as the reveal trailer. There was a comparison done. Outside of the time of day and different weather conditions, everything looks the same.
