No, Ryugu isn't a Borg ship; it's just very small, less than a kilometer in diameter, and each of the pixels in this image is about 300 meters across. So while Hayabusa2 can resolve the asteroid, that's not saying much. It'll be a while yet before we can see if Ryugu has a markedly nonspherical shape, and even longer until we can see surface features. But we're on the way!
