Unsurprisingly, a stage from New Super Mario Bros. U will be in the Wii U version of Super Smash Bros., director Masahiro Sakurai revealed last night over Miiverse. The stage is titled “Mushroom Kingdom U”.
Sakurai added: “When Kamek casts a spell, the stage transforms drastically! That said, this is not what you would call a moving stage.”
Sakurai also revealed that the stage will be playable in the demo of Super Smash Bros. during E3 week.
