Will AOE: DE have new features or it's just a visual improvements?

In AOE: DE Announcement Trailer you didn’t talk about new features. So will it have features or it’s just a visual improvement? If it contains new features then what kind of a feature(Like new countries, new units, new heroes, new strategies, new ages, etc).

The developers have revealed several improvements to the gameplay experience, most of which revolve around a completely revamped user interface, without affecting the core gameplay.
