[COLLAPSE="E3 Trailer concept"]
It's E3, Reggie is up on the stage showcasing the Wii U and 3DS's lineup. They approach the end of the conference:
"Today, we have given you a taste of what is to come with the Wii U and 3DS. But that's not all. Masahiro Sakurai and his team Project Sora have begun working on new title in the Super Smash Bros. series. Each for the Wii U and the 3DS. Masahiro Sakurai hopes to bring a brand new experience to the Smash Bros. world. By bringing both the Wii U and 3DS, together..."
*rooms lighting dims*
*Screen lights up...*
*A cinematic begins much as it did in Melee and Brawl, with Mario, Link, Pikachu and Kirby meeting each other to face off*
*The characters begin fighting in grand cinematic display until Kirby is star KO'd. He hits the screen, prompting a laugh from the audience. But when he does the screen begins to crack... He falls forward, outside of a 3DS... Kirby looks around in amazement. The others stop fighting and decide to look out in the open too. Soon every character is outside of the console in a bare white room, looking around. Lying behind them as they walk away will be a 3DS and Wii U tablet on the ground*
*Then the logo will display, Super Smash Bros. Royale. Personally would have preferred Strife, but I guess it has that whimsical, action oriented sound about it?*
*We finally get to a mixture of gameplay mechanics and animation as shown with Brawl. The gameplay will take place in Hyrule Castle, Geothermal Power Plant, Starship Mario and Battlefield. You will come to a point where there will be an animated segment that takes place in the Geothermal Power Plant. Mario and the other three will be fighting until something emerges from the lava below. The characters turn to face the emerging foe... Ridley is then seen! A bar with the word "Newcomer" is seen, the audience reaction is exstaticism. He flies down to the field and the animation transitions to aa small gameplay clip. Showing him sweep at his foes and grab Mario, dragging him across the ground and launching him forward.*
*It switches back to animation and the character are struggling to fight Ridley as he pushes them towards the lava. Until a large blast is shot at Ridley, causing him to reel. Out of the air emerges and landing on the stage is familiar face to some, Saki Amamiya. He pulls his head up and the word "Newcomer" is displayed once again, transitioning to gameplay of Saki beating the crap out of Ridley.*
*Once over Ridley grabs all of the five characters and starts flying towards the ceiling, crashing through and emerging from the ground into the air (it's not canon, remember?) Knocking over a certain familiar face... Once the characters break free and are upon the crowd, cowering behind them is Toad. Confused and scared he shivers a bit, "Newcomer" is displayed. In a scared panic he screams and actually runs TOWARDS Ridley, prompting a gameplay clip where he isn't so scared.*
*Ridley is seen gasping, exhausted from battle until reinforcement arrives... As the characters move forward the skies begin to grow dark and a figure materializes itself. With the image of snakes snapping in the air and a staff in hand, Medusa presents herself with our much expected "Newcomer" label and gameplay clip.*
*Afterwards the two villains and six heroes will be set on opposing sides, Medusa will then dissapear with Ridley in hand. The heroes will look around, confused as much of the audience. Then the camera zooms out from the characters to the logo displayed once again with jingle in tune... The screen goes dark... For about a few seconds the screen is dark and nothing is heard... Until this song begins to play:*

*Megaman X has arrived! He warps onto stage, throwing his arms out. The audience goes wild! A short trailer for Megaman X is shown displaying his gameplay, spanning across a couple of the stages already seen. Then at a point in the video Mario and Megaman X come together and begin an almost fighting, symbolic of two of the platform greats going head to head!*
*People are in both shock and confusion, it is Megaman alright. Just not Classic. Many questions are mumbled from the audience. "YES!!!!!!!" "I thought we'd get Classic for sure?" "Who cares, at least Megaman X is finally in a fighting game!" "Will we see anything from Classic Megaman?"*
*But most people will be buzzed from what they just saw*[/COLLAPSE]
