Namco Bandai's Yoshito Higuchi would love a Tales character to appear in Smash Bros Wii U but it seems that Masahiro Sakurai is cool on the prospect of featuring non-Nintendo characters in the next Smash Bros game.
Super Smash Bros Brawl introduced Konami's Solid Snake and Sega's Sonic The Hedgehog but it seems that their appearance could be a one off.
"I think Snake and Sonic joining were fantastic," Smash Bros creator Sakurai told IGN. "It made many fans happy, and it broadened the Smash Bros arena. However, introducing more non-Nintendo characters willy-nilly will lose the focus of the game, so I also recognise the need to narrow it down."
Recently, Sakurai said that Nintendo may have reached its limit in terms of character numbers with Brawl, suggesting that Smash Bros Wii U may not feature more characters.
