Several new "Pokémon Sun and Moon" trailers have been released. One of them may have the key to the four islands of Alola Region.

Nintendo Inquirer reported that a screenshot of a new Pokedex in one of the new "Pokémon Sun and Moon" trailers, which were posted on the game's Japanese YouTube channel, has revealed two different Pokedexes. These are the Alola Pokedex and the MeleMele Pokedex.

The two new Pokedexes were shown along with three blank spots. This led to speculations that the Alola Pokedex is for all Pokémon in the Alola Region.

Meanwhile, the MeleMele Pokedex may be "island-specific," similar to the Central, Coast and Mountain Kalos Pokedexes. These Pokedexes were specific to regions of Kalos in "Pokémon X and Y."

The publication noted that players could start out on MeleMele Island. It means "yellow" in Hawaiian. It may be safe to assume that the other islands will also be named after the first generation Pokémon games such as UlaUla (Red) Island, Polu (Blue) Island and OmaOma (Green) Island.

According to The Inquisitr, the new "Pokémon Sun and Moon" trailer showcased the game's w Rotom-infused Pokedex. It can now talk to players and guide them with a real-time mapping application as well as show them what type of Pokémon they have encountered.

GamenGuide reported that Nintendo has announced a Pokémon Special at the E3 2016. The event will be from Jun. 14 to 16 at the Los Angeles Convention Center.

The "Pokémon Sun and Moon" release date is slated for Nov. 18 in Japan and North America. Fans in Europe can get the game on Nov. 23.
