We learned a ton of new information about Super Smash Bros. Ultimate during Nintendo's latest Direct. The company shared more details on many of the game's features and revealed five new characters that'll be joining the roster. According to game director Masahiro Sakurai, those won't be the only newcomers appearing in the title.

During the presentation, Sakurai teased that there are still "a few" unannounced fighters in Super Smash Bros. Ultimate. He didn't provide any hints as to their identities, but he did confirm that Nintendo plans to unveil every character before the game launches, so fans won't have to wait until December to learn the entire roster.
