Please note: If your are looking for confirmed info on the next SSB game, then go to Super Smash Bros. 4. This page is about analysing the screenshots and trailers and making predictions on what certain things are. This article is about a game yet to be released.
I'll start by analysing the trailers. Near the middle of the Mega Man Trailer, Mario is hit by Mega Man's metal blade, and acts like Sonic the Hedgehog, losing his coins and getting knocked backwards. Seeing that Nintendo has done things like this in the past (making a person act like another person, and then announcing the other person), it's a possibility that Sonic will return.
Also in the Mega Man Trailer (at the end) and in some screenshots, we see the Yellow Devil, a boss from the first Mega Man game. He could be an Assist Trophy. However, he has only been shown in the Dr. Wily's Castle stage from the Mega Man series. This could mean that some multiplayer stages will appear in the story mode, and some may have bosses like the Yellow Devil.
Next, I'll be examining 3 photos that Mr. Sakurai has released. The first one is a pic of Mr. Sakurai celebrating a victory in a SSB4 demo at E3. In the background, you can see the results screen of his fight. It has a close-up of the winner, Mega Man, with none of the other fighter/s in sight. This could mean a little-ish celebration cut-scene for each fighter when they win a fight.
Photo number 2 is a pic of Mr. Sakurai playing the game by himself with 2 Wii U Pro Controllers (he was controlling 2 fighters at the same time. Does this mean that you won't be able to play with Wiimotes or the Wii U Gamepad?
Photo number 3 shows a drawing on a whiteboard. It features some fighters and items. There were some unconfirmed fighters in the drawing. They were Marth, Wario, Mr. Game&Watch, Meta Knight and Master Hand. This could mean they will be playable.
Before the E3 2013 trailer was first seen and hardly any info had been announced, Mr. Sakurai had said that he was drawing 3D images of Takamaru from Nazo No Murasame Jo and Little Mac from Punch-Out!!! This could mean that they'll join the game.
Whenever I make more analysis's, I'll post them here. Multus Valde (talk) 06:55, 21 July 2013 (EDT)Multus_Valde
