Yes, those are all that are currently available. Yesterday there was a massive hunt for a "secret map" but as it turned out, the mysterious map known as Podium that we found in the game files is only the area in which we do character creation. In the Future, maybe there will be more maps, but for now the ones you listed above are the only ones available to all players. As moonlight said, you could always make your own map or you could even go to the downloads section and download maps created by other people. Enjoy the game for now!
