Nintendo finally showed off their successor to the Wii U (and 3DS??), codenamed NX and officially now christened as Nintendo Switch, with a trailer at 7 a.m. PDT, just minutes ago as I begin typing this. Cartridges! Detachable controllers! Tiny-ass portable two player gaming! Splatoon! A new Mario! Trailer below, for posterity. You probably saw it already elsewhere!
