3DS

Get your grains of salt ready, this is all based on rumors from a NeoGAF thread that claims a verified source at Nintendo leaked this info. A NeoGAF mod has backed the poster's claim, but you should by no means assume this means it's all fact.

Supposedly, the NX console (with the new Legend of Zelda in tow) will launch during the holiday season this year. What other games will launch with NX remains unknown, but the leaker did provide a list of 3DS games for the year which includes code-named titles such as "Caviar F," "Torte City," "N-Stars," and "Pokémon Niji," which translates to rainbow in Japanese. The leaker warned that rainbow is just a codename and does not reflect the content of the game, but obviously the internet is stoked about the prospect anyway.

Rumors of a Pokémon Rainbow game have been around for years, but a game celebrating previous generations (hence the rainbow theme) would be well timed for the 20th anniversary of the series.

According to Japan's Corocoro magazine, the latest Pokémon Mystery Dungeon, Pokémon Mystery Dungeon: Magna Gate and The Maze of Infinity will be out on the 3DS this winter in Japan. The Corocoro article calls the game "totally new" and "totally different" from Pokémon games up to now.

I hope this were real. :(

The premise of The Thieves and the 1,000 Pokémon is to befriend and collect Pokémon through StreetPass. You can use Pokémon to take on the band of thieves and their Pokémon by clashing in stampede-style battles to retrieve stolen treasure.

If you don't have enough Pokémon, you'll end up losing against the thieves, so you'll actually need to have quite a lot of Pokémon to get far in the game. The villains are characters who'll be appearing in the upcoming film, Pokémon the Movie: Diancie and the Cocoon of Destruction.

The trailer also mentions that there's a special something in store for those who play the game and take it to the movie theaters when the new Pokémon movie premieres. There will also be something special for those with Pokémon X and Y.
