It has been recently announced that Pokemon Sun and Moon information will be revealed on May 10th at 9:00 PM in Japan. (5:00 AM in California and 8:00 AM in New York) Its not clear how the news will be released but my guess is maybe a Pokemon Direct? We'll find out pretty soon. Due to some rumors about the names of the Legendary pokemon of each game ( Solgaleo and Lunaala) we can expect this information to be regarding the legendary pokemon and confirming the names above if they are in fact that actual names.
