To finnaly clear things up some people have been wondering how long is kingdom hearts! well the only answer is what nomura said himself. Kingdom hearts will range around 30-40 hours like its predecessor. But the overall worlds will be up to 2 times larger. (imagine the hollow bastion war scene)
so thats what he meant when he said kingdom hearts would be up to two times larger.
