Have to keep in mind that this is selected screenshots and most likely picked to get away from the WoW comparison but I have to say that some of them look really good and the goblins are just awesome :)

As for grass, tree textures and other environment details we know from the latest DAOC expansion what Mythic is able to do with this engine and we know that they will improve on them over the life of the game. I'm not surprised at all at how good they look and wouldn't be surprised to see them gain more polish as the game develops, I sure hope my old gfx card will allow me to play the game though :/
