While Nintendo remains silent on NX, the rumor mill keeps turning. Emily Rogers, known for leaking games and details ahead of time, has tweeted out that four Wii U games are currently being ported to NX. We've heard before that Super Smash Bros. and the upcoming Zelda game could come to NX, and Rogers is certain they will. Rogers also states that ports of Super Mario Maker and Splatoon are in development for NX, but it's possible that they won't make the cut, as Nintendo is unsure how they'll transfer the current user bases or how they'll implement the two games' control schemes on NX. Rogers claims to have spoken to "at least ten" sources regarding this information.
Following this, a verified Reddit user posted a series of rumors regarding NX. In addition to corroborating the rumors about the four possible NX ports, the Reddit user claims that (according to four different sources) NX will be more powerful than PlayStation 4 "by a noticeable amount." We've heard various conflicting reports about the power levels of NX, so it's hard to say if that tidbit holds any water. As always, take rumors with a grain of salt.
