I had this idea that before E3 2013, a teaser trailer would be shown in a Nintendo Direct roughly a month or two before the real announcement at E3.
It would basically be a remake of the
Super Smash Bros. 64 intro, with the main difference being improved visuals using the Wii U's graphical capabilities. But it would be more then that, during the teaser there will also be new stages teased too and some minor cosmetic alterations with the character's moves and appearance.
But then it reaches around the end and instead of showing off Ness, Luigi, Captain Falcon, and Jigglypuff, it shows silhouettes of 4 newcomers.
Then it ends with a new Super Smash Bros. title which mixes blue and red colors, with a teasing "COMING SOON" flashing, the 3DS and Wii U logos, and the Nintendo and Namco Bandai logos on the bottom screen.
