Hello guys, I managed to get some information from a friend that has a familiar working on Nintendo and the next information is what I got:
*There will be an major Nintendo Direct coming on April and, as expected, a character will be revealed for the next Super Smash Bros., my friend told me that the specific character will be from the Fire Emblem series and who can this character be? If you all guessed on Chrom you were absolutely wrong...!! No, just kidding, Chrom will be announced as the new Fire Emblem this April.
*Second, Pac-Man was the character selected from Namco Bandai to be playable since all his back story he has with Nintendo. One of his special moves will be the Pac-Dive, and his final smash will be to transform all the players into ghosts and the only thing they can do it's run, Sakurai did this because it was a reference to the retro game.
*Sakurai wants to include the two most popular recently characters. Who are they? Most likely it will be Shulk (Xenoblade) and Dillon (Dillon's Rolling Western) since the popularity they both have with such great games. Plus, they have stages on both versions.
*Stages that will get on both versions are: Wild West (Dillon's home stage), Prison Island (Shulk home stage), a Pac-Man based stage, Ice Climbers' home stage (Not the same as Brawl), and Final Destination.
*Lor Starcutter (Kirby) is only available on the Wii U version.
*Pushmo Park is an stage on the 3DS version and features Mallo on it.
*Not every assist trophy from Brawl will return.
*Xerneas who was revealed on October is an Pokeball Pokemon.
*The music heard in the first trailer is the main theme of the Main Menu and Battlefield.
*Meta Knight and Yoshi will be revealed on May 2 and Summer 2014 respectively.
*Wario, Ganondorf, Ness, and Captain Falcon return.
*Ike, Lucas, Wolf, R.O.B., and Snake doesn't return.
*Pkmn Trainer is reworked with a new set of Pokemon, and now it's named Pkmn Trainer 2.
That's all the information my friend got. An opinion of mine is that Chrom will be revealed on the 20th of April. See ya guys and I hope this is true cause I agree with most of the leak!
