SSB 3DS/WII U which caracters included?

Is there going to be a ssb 3ds/ wii u? Yes. Who says? ING .com says so. So which characters should make it? Well i say all of the characters from ssbb with the return of mewtwo and first character appearances of shadow the hedgehog, Sora and Riku (Kingdom Hearts), Cherrim (Zelda Skyward Sword). The new suites could include Shadow in his chaos emerald form, Mario in tanooki form, Sora and Riku in both KH 1 And KH 2 form. Some new stages could be skyloft (Zelda Skyward Sword), keyblade graveyard (KH) and others. What else would you guys like to see?
