Japan have just announced Pokémon Super Mystery Dungeon! :D It will be released on 17th of September this year (damn waaaaait T_T) for the Nintendo 3DS.

And it has: ALL pokémon that are available in it! Your character can be any of the starting pokémon from generation I to VI! Including also Pikachu and a Riolu. :D

https://www.youtube.com/watch?v=NQNNXJky5CE Announcement trailer, that is soooooo awesome! It has so many favorites of mine it it! :D Zekrom, Reshiram, Latios, Latias, Dialga, Entei, Lugia, Deoxys and more! Even Arceus is in a screenshot I found on Serebii.net :O

Sorry if I seem super psyched but... Gates to Infinity mainly had the Generation V pokémon in it and not all of them either.

In this Pokémon SUPER Mystery Dungeon, it is slated to have EVERYONE of them in it! Now that is a huge step from GTI indeed in terms of how many pokémon you can encounter and possibly recruit. :O
