I'm not really sure why and how this happened but I created a new map on my superflat creative world and in the map you see hills, rivers etc.
Edit: I think that this has to do with the new seeds

Is this still a concern in the current Minecraft version 1.7.4 / Launcher version 1.3.7 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
