The current issue of Dengeki Nintendo magazine promises it will announce a new Pokemon game in its May 21st issue; it is stated in the blue sentence in the scan below. Since magazines other thanCoroCoro usually announce new games far after other sources, it's very likely we'll have the news before then. Could the game be the next Pokemon Battle Revolution? The first Pokemon 3DS game? Or a Speculated Ruby/Sapphire remake we will soon find out.
