I managed to get some information about the new Smash Brothers game.
-Target release is in July after E3 2014.
-Game is near completion and ahead of schedule. All characters, stages, and items have been completed. There are no cuts.
-A demo has been planned for E3. It will include Mario, Link, Pikachu, Kirby, and Samus. Battlefield will be the only available stage. Items are disabled.
-The official release date will be announced at E3.
-Ridley, Pac-Man, and Takamaru will be revealed at E3 to help create hype not only for Smash Bros but a new Metroid game, a new Pac-Man game, and a new Murasame Castle game.
-Ridley uses his design from Other M.
-Mii is another newcomer, but I do not know when he will be revealed, just not at E3.
-There will be unlockable costumes for the characters, such as Dr. Mario for Mario and Dark Samus for Samus.
-A new customization feature has been added, which will allow you to make your own costumes for your characters.
-The stage builder has been greatly improved on. 10 different themes/textures will come with the game. At least 5 will be series based and 3 will be original.
-As previously stated, there are no cuts so Snake will indeed return.
-He will revealed during a direct that will also announce a new Metal Gear Solid title for the Wii U.
