The Official Nintendo Magazine [UK] has announced that the game called “Pokémon AR Searcher” in Japan will be released under the English name “Pokémon Dream Radar”, at least in the United Kingdom. It will most likely be the global English title however. Its release date was also confirmed to be Autumn 2012 around the same time as Pokémon Black 2 / White 2 and Pokédex Pro.
Professor Burnett will task you with finding Pokémon in a place between the real world and the Pokémon world called “Dream Valley”. Sounds like a trip!
