Yes, this is not a drill.
Super Mario Bros. 3 is set to arrive on the 3DS and Wii U Virtual Console in North America on April 17.
Along with the announcement of several Game Boy Advance titles heading to the Wii U in April, it was announced that the 1988 NES classic will be arriving stateside in April. Announced some time ago for both systems, there had been much speculation as to why there hadn't been a release yet.
