Nintendo has just launched a teaser website for Super Mario 3D World on the Switch, fueling rumors about a looming new Nintendo Direct.

Yesterday, we reported that Nintendo recently updated its official Nintendo Direct Archive website, which might suggest that Nintendo will be airing a new Direct broadcast shortly. Although this is merely speculation at this point, the freshly launched teaser page for the upcoming Switch version of Super Mario 3D World + Bowser’s Fury does add to the possibility of Nintendo airing a new Direct soon.
